Dna rna结构区别
WebRNA, abbreviation of ribonucleic acid, complex compound of high molecular weight that functions in cellular protein synthesis and replaces DNA (deoxyribonucleic acid) as a carrier of genetic codes in some viruses. RNA consists of ribose nucleotides (nitrogenous bases appended to a ribose sugar) attached by phosphodiester bonds, forming strands of … WebDNA는 이중나사라는 특성 상 분자 자체의 안정성도 높고, 양쪽 가닥에 이중으로 정보를 보관할 수 있기 때문에 정보 보관에 훨씬 유리 합니다. 반면 RNA는 단일가닥이기때문에 분자의 안정성이 상대적으로 낮고, 정보가 손실되었을 때 복구하기가 매우 어렵습니다 ...
