Which of the following conclusions is most clearly supported by the representations of nucleic acid #1 and nucleic acid #2 ? Nucleic acid #1 contains only purines, whereas nucleic acid #2 contains only pyrimidines. Nucleic acid #1 contains only purines, whereas nucleic acid #2 contains only pyrimidines. A Nucleic acid #1 contains the sugar ribose, whereas nucleic acid #2 contains the sugar deoxyribose. Nucleic acid #1 contains the sugar ribose, whereas nucleic acid #2 contains the sugar deoxyribose. B Nucleic acid #1 contains positively charged phosphate groups, whereas nucleic acid #2 does not. Nucleic acid #1 contains positively charged phosphate groups, whereas nucleic acid #2 does not. C Nucleic acid #1 contains adenine-thymine base pairs, whereas nucleic acid #2 does not.

This question is incomplete

Explanation:

This question is incomplete but the keys words in the question provides an idea of what the completed question is.

There are two types of nucleic acid; ribonucleic acid (RNA) and deoxyribonucleic acid (DNA).

They are both made up of ribose/pentose sugar, nitrogenous base and phosphate group.

The ribose sugar of the DNA is one oxygen less than the ribose sugar of the RNA hence the reason for the name "deoxyribose".

There are five nitrogenous bases namely; adenine, thymine, guanine, cytosine and uracil. They both contain adenine, guanine and cytosine; however, the DNA contains thymine while the RNA contains uracil. Of the five bases, adenine and guanine are the purines (have a double ring structure) while the rest are pyrimidines (have a single ring structure).

The phosphate group here is negatively charged

it takes hundreds of years to become stable.

if you have another question lmk.
