They generally test for infections, changes in body tissue and organs, and they test for the presence of chemicals such as drugs or poisons.
The four nitrogen bases contribute to the variation between humans because the order of nucleotides determines phenotypic features associated with genetic inheritance.
- In DNA, there are four types of nucleotides, each containing one different nitrogen base.
- The four nitrogen bases in DNA nucleotides are Adenine, Guanine, Cytosine, and Thymine.
- The linear order of these nucleotides in genes largely determines the phenotypic features associated with genetic inheritance.
In conclusion, the four nitrogen bases contribute to the variation between humans because the order of nucleotides determines phenotypic features associated with genetic inheritance.

There are two phases of cell division, the <u>mitosi</u><u>s</u> and the <u>meios</u><u>is</u> phase. During interphase, the cell does <u>not split</u> ; it merely grows. Mitosis is the type of cell division that produces <u>two</u><u> </u><u>identical</u><u> </u><u>cells</u> with the same number of chromosomes. Mitosis is divided into four stages namely <u>prophase, metaphase, anaphase, </u>and<u> telophase</u><u>.</u>
