There are 8,324,608 possible combinations of 23 chromosome pairs. As a result, two gametes virtually never have exactly the same combination of chromosomes. Each chromosome contains dozens to thousands of different genes.
Guanine-cytosine is one of the nucleotide pairs that would be found in a DNA molecule. The other is Adenine- Thiamine.
Explanation:
Pyrine bases – Adenine & Guanine- pair with pyrimidines bases – Cytosine and Thiamine. Adenine pairs with Thiamine while Cytosine pairs with Guanine.
In RNA, however, while this same principle of base pairing is observed, rather than Thinmaine, RNA has Uracil in its place. Therefore, in RNA, Adenine pairs with Uracil. There is no Thiamine in RNA.

It shows the evolution of certain species through the bone structures of the fossils.
Tryptophan is specified by one single codon, which is what makes it so unique since it’s the only amnio acid that has one codon.
