PATHOLOGY

Detailed explanation-1: -A chromatid is one of the two identical halves of a chromosome that has been replicated in preparation for cell division. The two “sister” chromatids are joined at a constricted region of the chromosome called the centromere.

Detailed explanation-2: -Chromatin in the nucleus condenses to form double-rod structures called chromosomes. Looks like an “X”. Each chromosome has two rods because the cell’s DNA has replicated, and each rod in a chromosome is an exact copy of the other.

Detailed explanation-3: -Within cells, chromatin usually folds into characteristic formations called chromosomes. Each chromosome contains a single double-stranded piece of DNA along with the aforementioned packaging proteins.

Detailed explanation-4: -Chromosomes are found carrying your DNA in the nucleus of your cells. DNA looks like a spiral staircase (double helix). The rungs are base pairs and the rails are sugar and phosphate molecules.

Detailed explanation-5: -A telocentric chromosome is a chromosome in which the centromere is located at the terminal end of the chromosome and their shape is similar to the letter i or is rod-shaped. So, the correct answer is ‘Telocentric’.
