Types of RNA

(MRNA is) is a portion RNA that carries information from DNA to the ribosome, protein synthesis in cells (translated) RNA. I have determined the amino acid sequence of the protein coding sequence of the mRNA is produced. However, RNA, many do not encode a protein. It may be encoded (“non-coding”) (RNA gene), the gene own, but a so-called non-coding RNA, these may be derived from introns mRNA. One involved in the conversion process is also the most important cases of ribosomal RNA coding RNA transcription and RNA (of tRNA) of the (rRNA). Gene regulation, RNA processing, and there is also a non-coding RNA that is involved in other roles. It is possible to cut the catalyst of the peptide bond formation and RNA molecules other ribosomal RNA some such to catalyze chemical reactions such as ligation, these are known as ribozymes.

I carry the information ribosomal RNA within the cell (mRNA is), about the protein sequences of plant protein synthesis. This is encoded nucleotides each three (codon) so as to correspond to one amino acid. In eukaryotic cells, mRNA precursor transcribed from DNA as the (pre-mRNA), are processed in the mature mRNA. This eliminates all introns, non-coding region of the pre-mRNA. Then, from the nucleus, mRNA is exported to the cytoplasm it binds to its translation into protein and mRNA preparation and ribosome. In prokaryotic cells do not have compartments nucleus and cytoplasm at all, in a state in which the mRNA is transcribed from DNA, it can be combined with the ribosome. After a certain period of time, the message is decomposed into component nucleotides using ribonuclease.

carries a particular amino acid to the polypeptide chain transfer RNA (tRNA is) growing on the site of ribosomal protein synthesis during translation, it is a small RNA chain of about 80 nucleotides. This has a portion connecting the anticodon region and amino acids for codon recognition that binds to a specific sequence of messenger RNA chains via hydrogen bonding. Ribosomal RNA is the (rRNA), is a catalyst component of the ribosome. The ribosome of eukaryotes, rRNA molecule of four types are included: the 5S rRNA 18S, 5.8S, and 28S. Be synthesized nucleolus of three ribosomal RNA molecule, one is synthesized elsewhere. In the cytoplasm, combine to form a core protein and ribosomal RNA called ribosomes. Bind to mRNA, ribosome performs protein synthesis. Several ribozymes can be connected to mRNA at any time. All RNA is rRNA of most found in eukaryotic cells typical. Transfer RNA (tmRNA) is included in the protists and many bacteria. It tagged proteins encoded by the mRNA stop codons in the degradation of not preventing the ribosome from stalling.

Able to inhibit gene expression, several species of RNA is complementary to mRNA or DNA gene it. The micro-RNA, can be cleaved complementary mRNA or the translation is accelerated degradation by blocking mRNA, effector complex of miRNA’s and enzymes, and eukaryotes through (RNAi) RNA interference It is found in the act of. On the other hand small interfering RNA; is (Sirna 20-25 NT), in many cases, degradation of viral RNA, and is generated by the source of endogenous siRNA. As with the miRNA, siRNA acts by RNA interference. Causing the target gene is methylated, thereby, siRNA and miRNA Some may be increased or decreased transcription of these genes. And a PIWI-RNA interactions are considered animals are active in germ cells were protected from transposons, and plays a role in gametogenesis.

Prokaryotic Many have a CRISPR RNA regulatory system similar to RNA interference. Antisense RNA, widespread suppressor gene most, some, it is the activation of transcription. One way antisense RNA is able to act by forming a double-stranded RNA that is enzymatically degraded, binding to mRNA. There is a long non-coding RNA of many that regulate eukaryotic genes, covering the X chromosome of one of the female mammals, RNA such one is inactivated XIST, it. Cis-regulatory elements thereof that modulate the activity 3 ‘untranslated region or 5’ untranslated region of mRNA, MRNA may include a regulatory element itself such as a riboswitch. The untranslated region may also include regulatory elements of other genes.

RNA many involved to change the other RNA. Including to see can be intron ribozyme small nuclear RNA or several, (of snRNA) is canceled by myself, introns are spliced ​​pre-mRNA from the spliceosome. Located y Kaharubodi and nucleoli that can be changed by varying the nucleotides similar to other nucleotides A, C, in U. and G, in eukaryotes, RNA is modified nucleotides, the RNA, is, they are referred to a small nucleolar RNA by (60-300 NT snoRNA) in general. snoRNAs, when associated with the enzyme, I lead them to the location of the RNA from basepairing of this RNA. These enzymes, run the nucleotide subsequent changes. tRNA and rRNAs are vary widely, but you can be the subject of base modifications snRNA dove mRNA. It is possible to methylation of RNA.
