Answer:
G - 21%
T - 29%
A - 29%
Explanation:
Nucleotide bases in DNA are complementary. Adenosine (A) binds to Thymine (T) while Cytosine (C) binds to Guanine (G). Hence the composition of A in DNA is the same as that of T; and that of C is the same as that of G.
From the information given, C is 21%
Therefore G is also 21% of the genome as C is bound to G, the therefore are the same proportion.
C and G make up 42% of the genome (that 21% + 21%).
The remaining 58% (100%-42%) is made up of A + T
Similarly the proportion of A is equal to that of T,
Hence A is 29% (half of 58%) and T is 29%.
When a cell divides it makes two whole new cells this process is called mitosis.

During extracting DNA from cheek, it is a classroom and standard protocols to students to used sports drink in their mouth as they scrape the inside cheek than water. The reason for this is the sports drink contains salt and concentration which is compatible with the cells inside the cheek. Additionally, another reason is sports drink prevent cells from damaging or breaking apart and releasing DNA before getting a sample.
