DNA Nucleotide Total

The total number of adenine (A), thymine (T), cytosine (C), and guanine (G) nucleotides in a DNA sequence must equal 10,000.

A=T Rule

In a given DNA sequence, the number of adenines (A) is equal to the number of thymines (T).

Percentage of Nucleotides

The percentage of a specific nucleotide in a DNA sequence is calculated by dividing the number of that nucleotide by the total number of nucleotides and multiplying by 100%.
