Which of the following processes r2(k vcyz9ss5s/+ mv.fo(aml v ;vhojt38 k,:cdcd,fkf:lw- hl0; a zis most directly involved in the formation of nucleic acids such a:o,:lvfh ; 8zck0a t3-v kljfdhwdc;,s DNA?
A. Hydrolysis
B. Condensation
C. Catabolism
D. Translation
参考答案: B
本题详细解析:
Nucleotides are linked together by conz(rbxagf(g4q;v u:d 7densation reactions to form molecules of DNA (Choice B). The formation of DNA requires the removal of water for the joining of smaller molecules to form a larger molecule.The joining of nu(zgfrad :;47xbuv(gqcleotides together can also be classified as an anabolic reaction but not as a catabolic reaction (Choice C). Catabolism is the breaking down of a large molecule into a smaller molecule. An example of catabolism is hydrolysis which is a reaction that breaks down a large molecule into a smaller molecule by adding water (Choice A).Translation is a process which follows the transcription of DNA (Choice D). It is where mRNA is used as a template by ribosomes to synthesize polypeptides.
