In many species, a small part of the entire sequence of the genome encodes a protein. For example, it is composed of exons, encoding a protein having more than 50% of human DNA that about 1.5 percent of the human genome consisting of non-coding repetitive sequences. Difference of extraordinary genome size and eukaryotic genome between species, or raison d’etre of non-coding DNA of many, however represent puzzle for many years known as “. The mystery of the C value” very C-value still, DNA sequences some that do not encode proteins, can be used to encode a functional non-coding RNA molecules involved in regulation of gene expression.

Non-coding DNA sequences of several plays a structural role in the chromosome. Several genes have typically contains centromere and telomeres, but it is important for the stability and function of chromosomes. It is false, the copy of the gene is inactivated by mutation in the form of large DNA to non-coding human. They can serve as raw genetic material to create a new gene through the process of divergence sometimes gene duplication, but these sequences are fossil molecules normally.

Generally, growth of the organism, development, reproduction, cell or cell division is dependent on the process is divided into daughter cells identical two. This requires a copy of all genes in the genome in a process called DNA replication of the first. Copies made by specific enzymes known as DNA polymerases is to “read” the one strand of synthesis of new complementary strand DNA, and are known as double-stranded template strand. Because they are held together by base-pairing of the sequence of the circuit of double helix DNA, to give copies full fidelity, as read by the enzyme, one circuit determines its complementary sequence. Is semi-conservative, ie it is inherited by each daughter cell, a copy of the genome, the process of DNA replication, contains a chain that is synthesized one new and one source of DNA.

After DNA replication is completed, should be separated into two copies of the genome physically cells are divided into membrane-bound cells in two separate. Bacteria and archaea – In prokaryotes, this is usually bound to the cell membrane, the two films made by a relatively simple process called binary fission of the circular genome are separated into daughter cells, such as entering film Recessed It can be divided into components of the cytoplasm of bound. Binary fission is compared with the rate of cell division of eukaryotic very fast. Separation processes and departments chromosome cytoplasm known eukaryotic cell division, or as a phase S while Occurs M during the period, during this phase the cell cycle, the cycle, a complex process known as DNA replication, is. In unicellular eukaryotes such as yeast, the portion of the asymmetric cytoplasmic to two daughter cells, resulting in many reproduction by budding is common.

Transmission of genetic material from one generation of cells to the next replication and is the basis of the link between molecular imaging and classic gene and molecular genetics,. Because the copy of the gene in the cells of the parents is included in the progeny cells, organisms, inherit the characteristics of the parents. To reproduce the asexual organism, offspring is a clone or genetic copy of the parent organism. The organisms of sexual reproduction, is a special form of cell division called meiosis, cells called germ cells, which are haploid spouse or child or is generated, contains only one copy of each gene. Gametes produced by the female is called the ova or eggs, which are produced by men, is called sperm. A single cell with gametes two fuses, each with one copy from the father and the copy number of two times the gene from the mother again to form the embryo.

During the process of meiotic cell division, the event called control or transgenic above, the length of the DNA of one can occur in the chromatid length exchange of DNA in sister chromatid respective sometimes there. Allele in staining are the same, but there is no effect if the result of the re-set is to link the allele otherwise vary them. The Mendelian principle of state assortment of independent, which is sorted independently inherited allele gametes for trait 1, it is because of the characteristics of different organisms are two genes of each parent for the characteristics of each It is linked to the alleles inherited. Do the same chromosome, which is actually true genes that are not located far from each other on the same chromosome. To a larger extent, the two genes are close to the side on the same chromosome, they are and will be included in the gametes, in many cases, they are very similar in nature does not have to be separated as it was very The intersection will be displayed as gene you have, it is unlikely is going to take place between them. This is known as genetic background.

Typically, DNA Functions linear eukaryotic chromosome, and occurs as a circular chromosome in prokaryotic DNA. Sets of chromosomes in the cell performs its genome, the human genome is divided into 46 chromosomes, and having from about 3 billion base pairs of DNA. Information carried by the DNA is carried in a sequence of fragments of DNA called genes. Is achieved by base pairing further transmission of genetic information of the gene. For example, in the transfer, when using the information within the gene, DNA sequence is copied into a complementary sequence of the RNA by the attraction between nucleotides correct RNA and DNA to cells. Normally, then, in a process called translation same depending on the interaction between nucleotides of RNA, the RNA copy was used to make a matching protein sequence. In a different manner, the cell in a process called DNA replication simply, you can copy its genetic information. For more information about these features, focusing on the interaction with other molecules that mediate the function of the genome and DNA, here, we, are described in other articles.

Biologist, had a difficulty to adopt DNA Functions as genetic material of apparent simplicity of the chemical in the 1940s. The DNA, which is composed of only four kinds of similar sub-units to each other polymers chemically very known. In the early 1950s, the DNA molecule, was examined by X-ray analysis for determining the three-dimensional atomic structure (Chapter 8) first. It is shown that at the beginning of the X-ray diffraction results, and is composed of two chains of the polymer coil the DNA is wound. And is provided on one of the most important guidelines that DNA is double-stranded led to the Watson-Crick DNA structure and important observation. It is possible coding information and DNA replication is become apparent only when the model has been proposed. In this section, you will learn how to be able to take into account the structure of the DNA molecule, to store genetic information in general.

DNA functions molecule  is composed of two polynucleotide strands consisting of four types of nucleotide subunits. Each of these circuits is known as a DNA chain or DNA strand. I was held together the hydrogen bonds between the base moiety of nucleotides in both strands. As we see in Chapter 2, nucleotides, sugars consisting of five connected to the nitrogenous base and the phosphate group (s). In the case of nucleotides in DNA, the sugar is attached to (hence the name deoxyribonucleic acid) phosphate groups ribose, a single base, adenine (A), cytosine (C), or guanine (G), ( may be a T). Nucleotides alternating sugar thus covalent bond – are linked together in a chain by phosphate and sugar that forms the “backbone” (see Figure 4-3) phosphoric acid – phosphoric acid – sugar. The base only, each of four subunits, each polynucleotide strand of DNA is different, so it is similar necklace and (backbone) and informal (base of one 4, C, G, and T) in the beads of four . (A, C, G, and T) also numerals these based nucleotide four different Generally, sugar is used to ie shows the application of a group of phosphate.

It contains all of the genetic code that is used to control the development of the biological DNA function and behavior. The DNA also may be used as a long-term storage device for storing genetic instructions. DNA to be able to replicate itself, these instructions must be correct. Function of the DNA in the cell, is that the protein of the path encoding on or off the gene. Functions of DNA and DNA protein is the basis of life. This is a complex molecule consisting of four types of locations that are connected by putting stairs pass the ball to spiral. The four proteins of all, consistency each other each bind a couple of all, that you make all organisms other on earth and gene, to determine who you are. A replica of their nuclear DNA of an organism, all cells are (with some exceptions). This exception is the gametes, or sex cells of male and female to be used for playback. The order of the pair, is protected by the body cells, and strictly by dividing it into two parts, each time you play, DNA is copied to the new cell cell. Sometimes, there is a defect separation, but usually, the cell will be able to repair the damage.

DNA has been bundled with, 23 46 people posess chomosomes of which comes from cells of sex men and women of both the complex process to reduce to 23 from half chomosomes 46 of their own. New series of the entire design, which is designed to meet the bean sprouts, of chromosome 46, and therefore, I recombine with cells of another person to a whole new person. Half of each power of DNA ovum or egg, or (male) germ cells, sperm (female) you. Sperm enters the egg into two groups of 23 chomosomes, at the time of fertilization pregnancy, merge the gene structure complete thus complete 46 individual. Then, eggs initiates a complex process that is divided into two, then these cells, each copy of the DNA of the cell before divided into equal four. You can (or animal) all land has a DNA unique in nature and is used for positive identification of all people that way, but the only exception, is the identical twins . Set of dividing cells (called a blastocyst currently), for some reason, when I break in two years and split, they happen. This resulted in a DNA of another identical twins share one, therefore, leaves and characteristics, such as eye color such, the embryo of two which, generally, has the DNA of the same as how they look. They look like the same person. Some purposes, such as DNA throat basic idea quite this
