If thymine makes up 25% of the DNA nucleotides in the genome of a plant species, what are the percentages of the other nucleotides in the genome?

Adenine, Guanine and Cytosine takes 25% each

Explanation:

Recall that the sum of all nitrogenous bases in the DNA nucleotide is equal to 100%. And specific base pairings of Adenine to Thymine (A=T), and Cytosine to Guanine (C=G) must be equal.

So, the percentage of Adenine equal thymine, and that of cytosine equals guanine.

Now, A + T + C + G = 100%

So, if thymine makes up 25% of the DNA nucleotides, Adenine is also 25%.

Then, 25% + 25% + C + G = 100%

50% + C + G = 100%

C + G = 100% - 50% = 50%

Thus, divide 50% by 2 to obtain the individual percentage of cytosine and guanine. Each will take 25%

the correct answer should be false

{apex}

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
