- It is a double helix molecule.
- It consists of two chains of nucleotide strands.
- Every base have specific base that they match with A(adenine) matches with T(Thymine) and G(guanine) matches with C(cytosine)
- Bases have stages that fit together. A fits T and makes 2 H-bonds. Also, G fits C and makes 3 H-bonds.
- The amount of A, T, G and C in DNA can change from species to species.
- Always amount of A is equal to T,same for G to C,
- It has an ability to copy itself.
- Mainly found in the nucleus, also in mitochondria and chloroplast of all eukaryotic cells.
- In prokaryotic cells they are in cytoplasm.
