Best Answer: centerioles (or centrosomes--some books now call centrioles centrosomes but some books say only animal cells have centerioles) 2. centrosomes are found in plant cells 3.The interphase is a preparatory phase and during this the-nucleus and cytoplasm remain metabolically and synthetically active. The duplication of chromosomal DNA molecules takes place during the S phase of interphase.
A case study of coevolution. Genetic drift. Genetic drift â along with natural selection, mutation, and migration â is one of the basic mechanisms of evolution. In each generation, some individuals may, just by chance, leave behind a few more descendents (and genes, of course!) than other individuals.
