A gene has two sets of DNA.
During the S stage DNA synthesis occurs. (copying of the DNA)
True
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.
When a mistake happens in the process of copying DNA, the result is called a Mutation.
hot sauce
DNA replication happens during s-phase.
synthesis of DNA DNA Replication
DNA always remains in the sperm, that is how variation happens.
They would be bacteria
