Abstract: | Displacement loops are found in mitochondrial DNA isolated from the ovaries of mature female Xenopus laevis. These displacement loops subtend some 7% of the contour length of a mitochondrial circular DNA. When mature oocytes are shed as unfertilized eggs at least 76% of the mitochondrial DNA in these eggs contains displacement loops. The implications of these findings are discussed with respect to displacement loop occurrence in other mitochondrial DNAs and especially with respect to mitochondrial DNA replication. |
