染色体外的环状DNAeccDNA 是质粒吗?eccDNA到底是什么Extrachromosomal circular DNA
染色体外的环状DNA
eccDNA 是质粒吗?eccDNA到底是什么
Extrachromosomal circular DNA
染色体外的环状DNAeccDNA 是质粒吗?eccDNA到底是什么Extrachromosomal circular DNA
包括线粒体DNA、叶绿体DNA和质粒DNA
----------------------------------------------------------------
Extrachromosomal DNA (sometimes called extranuclear DNA or nonchromosomal DNA) is DNA located or maintained in a cell apart from the chromosomes.
In many cases,extrachromosomal DNA is contained in cytoplasmic organelles,such as mitochondria (animals),and in chloroplasts and plastids (plants).Extrachromosomal DNA can also be found in the plasmids of bacteria,or in intracellular parasites such as viruses.
应该是质粒dna,或者说主要是指质粒dna
染色体外的环状DNA应该指的是由染色体的小片段缺失而形成的环状DNA,存在于细胞核中,并不是线粒体DNA,叶绿体DNA和质粒DNA
除染色体以外的环状DNA
应该不是指质粒DNA,因为细菌的基因不能称为染色体
eccDNA应该是指线粒体DNA和叶绿体DNA
