What do Chromosomes Look Like?

Chromosomes look like strings. When chromosomes have been stained and are viewed under the microscope, you will see that a chromosome appears to be pinched in the middle. This is called the centromere, which is where the two ends of a chromosome join together. There are 46 chromosomes in a human, meaning there are 23 pairs. The size of a chromosome depends on the pair number of those chromosomes. .
