Detailed explanation-1: -DNA (deoxyribonucleic acid) is the cell’s genetic material, contained in chromosomes within the cell nucleus and mitochondria.
Detailed explanation-2: -Inside the nucleus, chromatin (DNA wrapped around proteins, described further below) is stored in a gel-like substance called nucleoplasm. Enclosing the nucleoplasm is the nuclear envelope, which is made up of two layers of membrane: an outer membrane and an inner membrane.
Detailed explanation-3: -Most DNA is found inside the nucleus of a cell, where it forms the chromosomes. Chromosomes have proteins called histones that bind to DNA. DNA has two strands that twist into the shape of a spiral ladder called a helix.
Detailed explanation-4: -DNA, deoxyribonu cleic acid, is the genetic material in your cells. It was passed on to you from your parents and determines your characteristics.
