Mitochondrial DNA. 2015 Aug;26(4):625-6. doi: 10.3109/19401736.2013.834434. Epub 2014 Jan 17.
Mitochondrial DNA plays an important role in living organisms, and has been used as a powerful molecular marker in various evolutionary studies. In this study, we determined the complete mitochondrial genome of Anas crecca (16,601 bp in length). Similar to the typical mtDNA of vertebrates, it contained 37 genes (13 protein-coding genes, 2 rRNA genes and 22 tRNA genes) and a non-coding region (D-loop). Overall base composition of the complete mitochondrial DNA was 29.05% A, 22.35% T, 32.64% C and 15.96% G.
线粒体DNA在生物体内发挥着重要作用，并已在各种进化研究中用作强大的分子标记。在本研究中，我们测定了绿头鸭的完整线粒体基因组（长度为16,601 bp）。与脊椎动物的典型线粒体DNA相似，它包含37个基因（13个蛋白质编码基因、2个rRNA基因和22个tRNA基因）和一个非编码区（D环）。完整线粒体DNA的总体碱基组成为29.05%A、22.35%T、32.64%C和15.96%G。
