two sets of sister chromatids that have synapsed
A gene has two sets of DNA.
DNA is made of 2 strands so when it replicates the strands separate and 2 new strands complete the old strands. leaving 4 strands making 2 sets of DNA, both sets of DNA consist of one old strand and one new strand.- Sierra A. Buchanan
True
During the S stage DNA synthesis occurs. (copying of the DNA)
what happen when dna letters are changed
DNA is copied.
It is a genetic trait governed by the person's DNA, and it's very rare.
You get two exact replica or the photocopies of DNA during splitting of DNA.
DNA splits, and mRNA and tRNA are there to create new strands for the new replicated DNA strand. This is what happens prior to mitosis in cell division.
