A typical skin cell has a diameter of about 0.0025 cm. The DNA in the nucleus of each cell codes for proteins. Proteins are involved in many aspects of how your body looks and how it works.

The DNA in the nucleus is part of a material called chromatin. Long strands of chromatin are usually bundled loosely within the nucleus.

A single strand of chromatin is made up of a long strand of DNA that is coiled around proteins.

Each strand of DNA contains 2 halves that are connected in the middle and twisted in a double helix.

When a cell is ready to divide, it has already copied its DNA. The copies stay attached as the chromatin is packaged into chromatids. The 2 identical form a chromosome.
