SSC MTS EXAM

Detailed explanation-1: -Genes are contained in chromosomes, which are in the cell nucleus. A chromosome contains hundreds to thousands of genes. Every normal human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes.

Detailed explanation-2: -Every cell in the human body carries a bundle of DNA in its nucleus-about three billion chemical nucleotides encoding roughly 30, 000 genes, discrete chunks of DNA that are translated into individual proteins. Each of the 46 chromosomes in a human cell’s nucleus bears thousands of genes.

Detailed explanation-3: -Chromosomes are structures that look like thread, which live in the nucleus (center) of cells. One molecule of DNA and one protein make up one chromosome. Chromosomes are different sizes, and proteins called histones allow them to pack up small enough to fit in a nucleus.
