NettetFeb 10, 2024 at 16:36. The existence of thymine in DNA instead of uracil is apparently due to evolution process which made DNA more stable. Thymine has greater resistance to photochemical mutation, making the genetic message more stable. A rough explanation of why thymine is more protected then uracil, can be found in the article. Nettet6. jun. 2016 · It has the same sequence as that of its parent DNA strand. b. The RNA transcript is complimentary to the DNA from which it is transcribed. Instead of thymine, it has uracil, which complements the adenine of DNA. c. The RNA transcript is an exact replica of the DNA from which it is transcribed.

NettetWhich statement does not correctly describe structural differences between DNA and RNA? - RNA molecules are generally single-stranded. - RNA molecules have a lower molecular mass than DNA molecules. - RNA contains uracil instead of thymine. - The sugar in RNA has one more hydroxyl group than the sugar in DNA. - All of the … NettetDNA and RNA are different from their structure, functions, and stabilities. DNA has four nitrogen bases adenine, thymine, cytosine, and guanine and for RNA instead of thymine, it has uracil.

Nettet8. jan. 2024 · DNA and RNA are very similar. After all, RNA is supposed to be a copy of DNA. However, there are a few differences between the two molecules. The biggest difference is in their shape: DNA is a two-stranded molecule in the form of a double helix. RNA, on the other hand, is a single-stranded molecule. Nettet11. apr. 2024 · The nitrogenous base thymine is replaced by uracil in RNA, this being a key difference in protein synthesis. Also, DNA is more stable and has a higher molecular weight than RNA. This occurs because of the pentose deoxyribose in its structure instead of the ribose molecule. The location of DNA and RNA inside the cell is another key …

NettetRna definition, ribonucleic acid: any of a class of single-stranded molecules transcribed from DNA in the cell nucleus or in the mitochondrion or chloroplast, containing along the strand a linear sequence of nucleotide bases that is complementary to the DNA strand from which it is transcribed: the composition of the RNA molecule is identical with that … Nettet24. sep. 2024 · RNA contains uracil, while DNA contains thymine.
