WebApr 11, 2024 · The structure of RNA nucleotides is different from that of DNA; the nitrogenous bases, in this case, are guanine, cytosine, adenine, and uracil. For its part, the pentose used will be ribose, which is a more unstable molecule than DNA. RNA is involved in protein synthesis, using information from DNA to turn it into substances.

Difference Between DNA and RNA

WebRoles of DNA and RNA in cells. Nucleic acids, macromolecules made out of units called nucleotides, come in two naturally occurring varieties: deoxyribonucleic acid ( DNA) and ribonucleic acid ( RNA ). DNA is the … WebThe single-stranded DNA of the lagging strand created by the action of the helicase is covered by tightly binding single-stranded DNA-binding proteins.

WebDNA molecule is B-form double stranded helix while RNA molecule is A-form single stranded helix. b. DNA contains deoxyribose sugar while RNA contains ribose sugar that has more OH group than deoxyribose. c. DNA has small grooves in helix making it more stable than RNA-which has large grooves- under sudden changes as attacking enzymes … WebDNA uses deoxyribose in its backbone. RNA uses ribose. Why? When ribose is in the sugar-phosphate chain, the molecule is more flexible. Because RNA is single stranded and more flexible than DNA, RNA can bend and bond with itself. This in vital in tRNA as well as rRNA (ribosomal RNA) where it is the shape of the molecule that is important, not ... WebHowever, whereas DNA molecules are typically long and double stranded, RNA molecules are much shorter and are typically single stranded. RNA molecules perform a variety of roles in the cell but are mainly involved in the process of protein synthesis ( translation) and its regulation. RNA Structure 4p管理体系
