I NEED HELP 1.What are three ways the ability to copy DNA has changed our world?
2.How can personal DNA machines save human lives?
3. If you had access to a personal DNA machine, what would you analyze and why?

as in mitosis, dna replication occurs during interphase.   in meiosis, it occurs specifically in s phase of interphase 1.

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.

cells spend most of their time in interphase
