If 30% of the bases in a particular dna molecule are guanine(g), what percentage of the bases would be thymine(t)? explain your reasoning.

Since 30% of the bases are guanine, we know that 30% must also be cytosine (because it pairs with guanine in DNA).

Knowing this, we have figured out 60% out of 100%, leaving us with 40%.

Thymine pairs with Adenine, so Thymine and Adenine each make up 20% of the remaining 40% of the DNA in this example.

In total:

Guanine: 30%

Thymine: 20%

Cytosine: 30%

Adenine: 20%

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.
