DNA replicates itself exactly, it occurs in the S phase of interphase; essential before mitosis (nuclear, not cell, division) occurs to ensure the two daughter cells produced from the parent cell have exactly the same chromosome number
These molecules remain attached and form the twochromatids, joined by a centromere, that make up a chromosome visible in the prophase of mitosis
A) Chromosome
B) Chromatid
C) Centromere
Replication is semiconservative; this means that each new DNA molecule consists of one old strand and one new strand, the original parent strand acts as a template for the newly formed daughter strand
