Detailed explanation-1: -DNA (deoxyribonucleic acid) is the cell’s genetic material, contained in chromosomes within the cell nucleus and mitochondria. Except for certain cells (for example, sperm and egg cells and red blood cells), the cell nucleus contains 23 pairs of chromosomes. A chromosome contains many genes.
Detailed explanation-2: -The molecule inside cells that contains the genetic information responsible for the development and function of an organism. DNA molecules allow this information to be passed from one generation to the next.
Detailed explanation-3: -Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
Detailed explanation-4: -What carries the genetic information? Genetic information is all of the information stored in our DNA. DNA stands for “deoxyribonucleic acid.” The strands of DNA look like a twisted ladder, known as a double helix.
Detailed explanation-5: -In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes.
