- 33. The Reason Why DNA Replicates DNA replicates for inheritance. DNA replicates in Interphase by making a copy of itself before the cell splits. It can be made into a new cell or a new organism. This process occurs in the nucleus of the cell in eukaryotes and in the cytoplasm of prokaryotes.
- 34. Genetic Mutations Telomeres make chromosomes longer at the ends and they can make genetic mutations better by fixing them. Telomerase makes telomere make the chromosome longer so the genetic mutation can be gone faster. The difference between normal cells and cancer cells is that cancer cell can grow forever and never die but normal cells will. Transplanted cells are changed by putting different genes in them and they probably won’t develop into cancer.
- 35. Genetic Mutations cont. Cloning is when a scientist takes a cells nucleus from an organism and uses that nucleus to make the same organism entirely, only younger. During the process of aging, cells lose their telomerase.
