Document Summary
The cells in your body take on incredibly diverse shapes and functions even though the genetic material in each one of them is the same. Diversity in cellular and organismal phenotype across individuals of the same species is due to differences in their genotypes that give rise to differences in protein expression. In order for cells to divide, the dna in the (cid:498)mother(cid:499) cell must be faithfully replicated in order to ensure that both (cid:498)daughter(cid:499) cells have a full complement of chromosomes. Don"t worry about mitosis focus on replication as a whole. Two chromosomes are replicated into two diploid cells. During replication, the two strands of the parental duplex separate. The bases are paired in the parental duplex. Each parental strand serves as a template for synthesis of a new daughter strand. Dna polymerase: enzyme that catalyzes dna synthesis; they can work only in one direction and can add deoxyribonucleotides only to the 3 end of a growing dna chain.
