Answer/Explanation:
The difference between chromosomes and chromatids
During mitosis, the cell replicates its DNA and passes it onto two daughter cells.
After DNA replication, a chromosome is made up of two identical sister chromatids. When these are separated, they are divided into the two daughter cells so that each contains the genetic material.
When the chromatids are joined together in replicated DNA, they are called chromatids and form the chromosome. When they are divided and separated into two daughter cells, the sister chromatids are called chromosomes again.
Body goes through mitosis
The cells in your body go through mitosis when you need to grow. They divide to form new cells to increase the size of tissues. Mitosis also replaces damaged cells to repair tissues.
