NEET BIOLOGY

Detailed explanation-1: -(KROH-muh-some) A structure found inside the nucleus of a cell. A chromosome is made up of proteins and DNA organized into genes. Each cell normally contains 23 pairs of chromosomes.

Detailed explanation-2: -In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

Detailed explanation-3: -Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA).

Detailed explanation-4: -… Chromosomes are threadlike structures made of protein and a single molecule of DNA that serve to carry the genomic information from cell to cell. In plants and animals (including humans), chromosomes reside in the nucleus of cells.

Detailed explanation-5: -A single length of DNA is wrapped many times around lots of proteins? called histones, to form structures called nucleosomes. These nucleosomes then coil up tightly to create chromatin loops. The chromatin loops are then wrapped around each other to make a full chromosome.
