If a DNA sample were composed of 10 percent thymine what would be the percentage of guanine?

Answer 1

There are four different nucleobases including adenine, thymine, guanine and cytosine. Each nucleobase pairs with it's opposite, for example adenine pairs with thymine and guanine pairs with cytosine. Knowing this, if a DNA sample had 10% thymine that means it would have 10% adenine equalling 20% of the entire sample for the both of them. The remaining 80% of the sample would contain 40% cytosine and 40% guanine.

Answer 2

Since DNA base pairs are always complementary, the percentage of guanine would be 40 percent (10% thymine pairs with 40% adenine). DNA contains equal amounts of adenine-thymine and guanine-cytosine base pairs.

Answer 3

The proportion of cytocine and thymine is the same in a DNA molecule, therefore it will also contain 10 % thymine.

Answer 4

If DNA has 22% thymine then it will have 22% adenine. This leaves 56% for guanine and cytosine. That leads to 28 % of guanine and 28% cytosine.

Answer 5

40%

Answer 6

40
