Explanation:
Detailed explanation-1: -For example, the human genome-approximately 3.2 × 109 nucleotides-is distributed over 24 different chromosomes. Each chromosome consists of a single, enormously long linear DNA molecule associated with proteins that fold and pack the fine DNA thread into a more compact structure.
Detailed explanation-2: -Most human cells have 46 chromosomes, but occasionally, a glitch in cell division results in a cell with too few or too many chromosomes. When this happens in egg or sperm cells, the child can have an abnormal number of chromosomes.
Detailed explanation-3: -Our genetic information is stored in 23 pairs of chromosomes that vary widely in size and shape.
