An intact length of dna consists of 320 total nucleotides (160 nucleotides/strands). a total of 95 cytosine nitrogen bases are found in the entire segment. How many molecules of adenine would be found in the segment of dna?

65

Explanation:

The DNA segment has a total 95 cytosine bases. Since cytosine makes hydrogen bonds with guanine base, this means that the DNA segment has a total 95 guanine bases.

Total guanine + cytosine bases in the segment= 95 + 95 = 190

So, a total of adenine and thymine bases in the DNA segment= 320-190 = 130

Since the number of adenine and thymine bases are equal in a double-stranded DNA molecule, the number of adenine bases in the given segment would be= 130/2= 65

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
