Answer:
• 16% of the alien genome is comprised of G
• 12% of the alien genome is comprised of T
• 12% of the alien genome is comprised of A
• 22% of the alien genome is comprised of X
Explanation:
As given in the question above , we see that each nucleotide is complimentary to the other nucleotide, there cannot be an excess of one than the other.
Let's say,
C — G,
Meaning that the amount of C = the amount of G
So in the occurrence of approximately 16% of C in the genome implies that there is approximately 16% composition of G (for it to bond to) as it's pair.
The same logic comes in handy to determine the amount of nucleotide X present.
If Y binds to X
And approximately 22% of nucleotide Y is present, then the same percentage complement of nucleotide X is expected to be present say 22%.
Now all of the nucleotides have to add up to 100%, so:
A + T + G + C + X + Y = 100%
A + T + (16%) + (16%) + (22%) + (22%) = 100%
A + T = 24%
Given that A – T,
and A=T
Therefore, the amount of A is 12%, and the amount of T is also 12%.
