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.
Evolution is the process by which modern organisms have descended from ancient ancestors.
Gene flow is a process of evolution that takes place when genes or alleles move from one population to another. It is also known as the Gene Migration, and that could cause changes in the allele frequency as well as some variations in the gene pool of both populations.enetic Drift. Genetic drift is a mechanism of evolution of biological species that takes place because of the change in the frequency of alleles in a population. These changes in the allele frequency in a population occur randomly.
