Question

What is the difference between chromatids and chromosome?

Answer 1

Chromatids:

1. Chromatid is one among the two identical halves of a chromosome that has been replicated in preparation for cell division.
2. Chromatid is formed of chromatin fibers during both meiosis and mitosis.
3. It authorizes cells to store two copies of their information in preparation for cellular division.

Chromosomes:

1. A chromosome is a hyper-condensed, wound form of DNA molecules containing the genetic material of an organism.
2. Each chromosome is formed of DNA tightly coiled many times around proteins called histones.
3. The main function of chromosomes is to carry the DNA and transfer the genetic information from parents to offspring.

Chromatids	Chromosomes
1. Homologous sister chromatids are identical.	Homologous chromosomes are not always identical. each copy of the genes is contributed by a parent.
2. Chromatids are formed during cell division.	2. Chromosomes exist in their natural state throughout the lifecycle of an organism.
3. Chromatid is less condensed than a chromosome.	3. Chromosome is the most condensed form of DNA.
4. DNA of the chromatids is not utilized during DNA synthesis.	4. DNA is utilized during macromolecule synthesis.
