Answer:

The correct option is (A).

Explanation:

The base-pairing rule illustrates the pairing of purine and pyrimidine bases in the construction of nucleic acids. Adenine and guanine are purines and pyrimidines are cytosine, thymine, and uracil.The total number of base-pair defines the size of the genome of an organism.

Uracil is exclusively present in the RNA. We can infer that purine base pairs with pyrimidine. So, adenine pairs with thymine in the DNA strand with the help of two hydrogen bonds and guanine pairs with cytosine that is supported by the presence of three hydrogen bonds.  

In case of RNA adenine forms double bond with the uracil residue.

Alex

Answer:

Juan

Explanation:

Given the information from the question. We need to find out which person will get the best resolution and the reason thereafter. Since we know that the resolution is directly proportional or relative to N (A). Based on the information provided .Juan will have the best resolution due to higher N (A). Therefore, the correct answer is Juan.
