Detailed explanation-1: -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). Mitochondria are structures within cells that convert the energy from food into a form that cells can use.
Detailed explanation-2: -Genes are found on tiny spaghetti-like structures called chromosomes (say: KRO-moh-somes). And chromosomes are found inside cells. Your body is made of billions of cells. Cells are the very small units that make up all living things.
Detailed explanation-3: -Chromosomes carry DNA in cells. DNA is responsible for building and maintaining your human structure. Genes are segments of your DNA, which give you physical characteristics that make you unique.
Detailed explanation-4: -Genes are found in every one of the 37 trillion cells that make up our body. To define what a gene is, let’s look closer at one of those cells. Every cell has a nucleus and inside every nucleus are chromosomes and all chromosomes are made of DNA, molecules that contain genetic information called genes.
