The answer is a hair root.

Nuclear DNA is commonly extracted from the hair root. The hair root consists of keratinocytes. Keratinocytes are cells found in the epidermis. As all other cells, they contain DNA material. When keratynocites die, they get converted into keratoid material in the process of cornification. As a consequence, d<span>ead cells do not contain DNA material. Therefore, the hair root is the best source of nuclear DNA than shed or cut hair when working with hair sample.</span>

Why are cells so small? In your answer, use the terms volume, distance, diffusion, surface area, plasma membrane.
Leno4ka [110]

Answer:

Cells are so little, so they can maximize their ratio of surface area to volume.

Explanation:

Smaller cells have a higher ratio which allows more molecules and ions to move across the cell membrane per unit of cytoplasmic volume. Cells are so small because they need to be able to get the nutrients in and the waste out quickly.
