In a sample of double-stranded DNA, 10 percent of the nitrogenous bases are guanine (G). What percentage of the nitrogenous base

DanielleElmas [232]

Answer:

40%

Explanation:

Remember that guanine always pairs with cytosine, and thymine always pairs with adenine. That means that any time there is a guanine, there is always a cytosine.

If there are 10% guanines, then there are 10% cytosines. That means the total of guanines and cytosines is 20%.

The other 2 bases (thymine and adenine) have to make up the rest of the bases. That means they have to make up 100-20 = 80%.

Again, there will be equal amounts of thymine and adenine, so 80%/2 = 40%.

A medical test indicates that a patient has a defective protein. This

OleMash [197]

Answer:

number of nitrogen bases

Explanation:

The correct answer would be the number of nitrogen bases.

A defective protein is usually caused by mutation, which is defined a change in the DNA sequence of an organism.

Mutation can occur in a variety of ways including:

1. Deletion of nucleotide base sequence in the DNA

2. Addition (insertion) of nucleotide base sequence in the DNA

3. Duplication of nucleotide sequence in the DNA

A change in number of phosphate molecules, sequence of subunits DNA and sequence of sugar molecules if possible in nature, do not lead to mutation if the change does not affect the sequence of DNA.

Hence, the correct option is number of nitrogen bases.
