Hello. ImSARHIP from Blooming Minds Online Class. Now let's study about RNA and its types and properties. RNA, a abbreviation of ribonucleic acid, complex compound of high molecular weight that functions in cellular proteins synthesis and replaces DNA, the oxyribonucleic acid, as a carrier of genetic codes in some viruses. RNA consists of ribose nucleotides, nitrogenous bases depended to a ribose sugar, attached by phosphodiester bonds, forming strands of varying lengths. The nitrogenous bases in RNA are 89, Guanine, cytosine. RNA typically is a single stranded biopolymer. However, the presence of self-confimentary sequences in the RNA strand leads to intercane base pairing and folding of the ribonucleotide chain into complex structural forms consisting of bulges and helices. The three-dimensional structure of RNA is critical to its stability and function. RNA, its types and properties. In both perperiotes and nucleo-cariotes, there are three main types of RNA-dash messenger RNA, mRNA, ribosoma-lRNA, RNA, and transparRNA, TINA. Messenger RNA, mRNA. mRNA accounts for just 5% of the total RNA in the cell. mRNA is the most heterogeneous of the three types of RNA in terms of both base sequence and size. It carries complementary genetic code copied from DNA during transcription, in the form of triplets of nucleotides called codons. Each codon specifies a particular amino acid, the one amino acid may be coded for by many different codons. Although there are 64 possible codons or triplet bases in the genetic code, only 20 of them represent amino acids. There are also three stop codons, which indicate that ribosomes should cease protein generation by translation. As part of post-transcriptional processing in eukaryotes, the 5-end of mRNA is capped with the guanosine triphosphate nucleotide, which helps in mRNA recognition during translation or protein synthesis. Similarly, the three-end of an mRNA has a polyethyl or multiple-avilative residues added to it, which prevents enzymatic degradation of mRNA. With the 5-end and 3-end of an mRNA imparts stability to the mRNA. Ribosome the RNA, RUNA. RUNAs are found in the ribosomes in account for 80% of the total RNA present in the cell. Ribosomes are composed of a large subunit called the 50-s and a small subunit called the 30-s, each of which is made up of its own specific nanomolecules. Different RUNAs present in the ribosomes include small RUNAs and large RUNAs, which belong to the small and large subunits of the ribosome, respectively. RUNAs combine with proteins and enzymes in the cytoplasm to form ribosomes, which act as the cytoprotein synthesis. These complex structures travel along the mRNA molecule during translation and facilitate the assembly of amino acids to form a polypeptide chain. They interact with turners and other molecules that are crucial to protein synthesis. In bacteria, the small and large RUNAs contain about 1,503,000 nucleotides, respectively, whereas in humans, they had about 1,805,000 nucleotides, respectively. However, this structure and function of ribosomes is more shape than our fibospecies. The first part of the structure is the ribosome, which is the cytoprotein synthesis. This is the first part of the structure and the second part of the structure is the ribosome, which is the cytoprotein synthesis. This is the first part of the structure and the second part of the structure and the second part of the structure and the second part of the structure and the second part of the structure and the second part of the structure and the second part of the structure and the second part of the structure and the second part of the structure and the second part of the structure and the second part of the structure and the second part of the structure and the second part of the structure and the second part of the structure and the second part of the structure and the fourth, which are formed by methylation of the usual bases.
