A. Hydrolysis
B. Condensation
C. Catabolism
D. Translation
参考答案: B
本题详细解析:
Nucleotides are linked together by condensation reactions to form moe,tctgo:6miu8 )2xsc ; m1etl lecules 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 nucleotides 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 eg tt1tesm:,i ;2)6 lm8xocuecxample 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.
