DNA replication occurs because of the need of genes to be passed to new cells and so that the new cell can grow. This affects your body in good ways. But if that DNA is in a bad environment or two bases match wrong, it will cause the cell to grow wrong or the wrong genes wont be passed on to the new organism. This can also result in cancer for that organism or cell.
Telomeres are long stretches with chromosomes at the end that arent coded.
Okazaki Fragments is when replication opens, then DNA polymerase begin to synthesis the complementary strand.
DNA Ligase has to stich the Okazaki Fragments together.
Telomerase is a enzyme that adds telomere to the 3’ end of DNA strands. DNA Polymerase is able to synthesis the opposite strand.
Aging is a change that are universal. Aging damage occurs to molecules, cells, and organs.
Cancers to a normal tissue can grow indefinitely. Most 85-90% cancers express telomerase in the population, then divides uncontrollably causing a tumor to grow
Transplanted cells are removing cells from the patient, then transforming them with the gene for the product that the patient was was not synthesized. Then returns back to the patient where it started.
Cloning is the replication of a DNA starting with a single living cell to generate a large population of cells containing the same DNA molecules
