我想問問經有絲細胞分裂出來的"daughter cells" 會否與 "parent cells" 的 DNA 一樣呢? | ||

Dear 991150, 1. The daughter cells formed by mitosis are genetically identical to their parent cell. That means their DNA are identical. 2.In winter we heat lost very quickly because of the great difference in temperature. Therefore you are right that we need more energy to keep warm. |
