Amino acids with hydrophobic r groups are most often found buried in the interior of folded proteins.True or False.
Art [367]

The answer is; True

Since the body is mainly composed of water solutions, molecules in the body need to be hydrophilic to interact positively with the water. For proteins to dissolve well in the body the hydrophilic groups are located on the outside of the folded proteins while the hydrophobic groups are ‘hidden’ in the inside of the protein. If the hydrophobic parts were located in the outside, the proteins would clump up togetehr and interfere with their functions.

If 20% of a DNA sample is made up of thymine, T, what percentage of the sample is made up of cytosine, C?
anastassius [24]
DNA consists of four nitrogenous bases: A, T, C, and G. Because A and T form a pair and C and G form a pair, the percentage composition of A is equal to T and the percentage composition of C is equal to G. This is called Chargaff's Rule.

In this sample, 20% is T. Because the percent composition of A is equal to T, we can expect 20% to also be A. That means that A and T make up 40% of the sample. That leaves 60% of the sample as C and G. The percentage composition of C must be equal to G, so divide 60% by 2 to get 30% G and 30% C.

So the answer is 30%.
