Question

What is the term for the result when a single chromosome containing one strand of dna divides itself into two new chromosomes and two identical copies of dna are created?

Answer 1

Following replication, each chromosome is composed of two DNA molecules; in other words, DNA replication itself increases the amount of DNA but does not (yet) increase the number of chromosomes. The two identical copies—each forming one half of the replicated chromosome—are called chromatids.
