$\huge\color{Red}\boxed{ANSWER}$

$<b><i><u>✔️$ DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.


✔️DNA is deoxyribonucleic acid, and is contained in your body's cells. It is a double, long chain of molecules called nucleotides that tell each cell what proteins to make. The DNA itself makes up chromosomes.


✔️Nearly every cell in a person's body has the same DNA. 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).


✔️DNA is vital for all living beings – even plants. It is important for inheritance, coding for proteins and the genetic instruction guide for life and its processes. DNA holds the instructions for an organism's or each cell's development and reproduction and ultimately death.
