DNA stands for deoxyribonucleic acid. DNA is in all living things. Most cells in the human body have the same DNA inside of their cells. Most DNA is at the nucleus of a cell. Mitochondria are a part of a cell (“What is DNA?”).
DNA is also found in mitochondria. The DNA inside of mitochondria is called mitochondrial DNA or mtDNA (“What is DNA?”) .
Information in DNA is: adenine (A), guanine (G), cytosine (C), and thymine (T). These are known as bases. Human DNA has three billion bases. The sequence of the bases is how proteins know what to make (“What is DNA?”). …show more content…
Each base has a sugar molecule. A base, sugar and phosphate are called a nucleotide. A phosphate is a salt. These bases look like a ladder (“What is DNA?”).
The ladder is called a double helix. The bases form the ladder and the sugar molecules form the outside part. DNA can double which make more ladders (“What is
