Question

write a short note on tRNA

Answer 1

Hey mate here is your answer》》

RNA, which stands for ribonucleic acid, is a polymeric molecule made up of one or more nucleotides. Each nucleotide is made up of a base (adenine, cytosine, guanine, and uracil, typically abbreviated as A, C, G and U), a ribose sugar, and a phosphate.Double-stranded RNA (dsRNA) is RNA with two complementary strands, similar to the DNA found in all cells, but with the replacement of thymine by uracil. dsRNA forms the genetic material of some viruses (double-stranded RNA viruses).

Answer 2

Ribonucleic acid (RNA) is a biopolymer macromolecule as DNA. It consists of small subunits called nucleotides composed of:− Purine nucleobases [Adenine−(A), Guanine−(G)]− Pyrimidine nucleobases [Cytosine−(C), Uracil−(U)]− D-ribose pentose sugars [C5H10O5]− Phosphate groups [PO43-]The nucleobase is attached on the D−ribose by an N−glycosidic bondThe ribose is bonded to the phosphate group through ester bondsThe backbone bonding between RNA nuclotides (i.e. the bonds between the phosphate group and an adjacent ribose sugar) occurs through phosphodiester bonds. A phosphate group is attached to the 3'−carbon position of one ribose and on the 5'−carbon position of the next

Characteristics

RNA does not self replicate in order to multiply; instead it is encoded by DNA genesRNA is synthesized in order for the translation of DNA to be possibleThe DNA-RNA function is highly interdependable, i.e., if there is problem with DNA, there will be a problem with the RNA functions and vice versa (no RNA = no DNA translation can occur, thus DNA is useless without its RNA genes)
