The guanine percent is 30. This is because the other 30% of the 60% is cytosine. Getting back to adenine, it always partners up with thymine as i mentioned before, So it would be 20% thymine and 20% adenine, add those portions to the 60% of the other two, mentioned above and you have 100%.

Naily [24]
Hello,

The answer is option A "mitosis".

Reason:

Mitosis one of the stages of a cell where the cells are separated into two chromosomes therefore putting them into a nucleus. Its not option B because cytokinesis is another part and divides one cell into two daughter cells (which means this is involved of the sex of the child). Its also not D because transcription is involved in gene expression.

If you need anymore help feel free to ask me!

Hope this helps!
