A chromatid is one of two identical halves of a replicated chromosome. … Following DNA replication, the chromosome consists of two identical structures called sister chromatids, which are joined at the centromere.
What are strands of replicated chromosomes called?
A chromatid is a replicated chromosome having two daughter strands joined by a single centromere (the two strands separate during cell division to become individual chromosomes).
What is each strand of a duplicated chromosome?
Each DNA strand in the duplicated chromosome is referred to as a chromatid, or sister chromatid.
Which are the two main parts that make up a chromosome?
DNA is coiled around proteins called histones, which provide the structural support. Chromosomes help ensure that DNA is replicated and distributed appropriately during cell division. Each chromosome has a centromere, which divides the chromosome into two sections – the p (short) arm and the q (long) arm.
What is the structure of a duplicated chromosome?
A replicated chromosome (or equivalently, a duplicated chromosome) contains two identical chromatids, also called sister chromatids. The difference between a duplicated chromosome and a chromatid, strictly speaking, is that a chromosome contains two chromatids that are joined at a structure called a centromere.
What are the two parts of cell division?
There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells.
