DNA and RNA Structure

Question 1

Which represents a strand of RNA bases?

Revolt · Accepted Answer

UGGCUCGAA

Question 2

On an RNA molecule, which would base pair with adenine?

Revolt · Accepted Answer

uracil

Question 3

Where is the DNA located in a eukaryotic cell?

Revolt · Accepted Answer

nucleus

Question 4

Why can uracil be used as a “clue” to identify RNA in a strand?

Revolt · Accepted Answer

Because uracil is unique to RNA.

Question 5

The diagram shows a nucleic acid in the shape of a double helix.Which sugar is present in the nucleic acid that is represented in the diagram?

Revolt · Accepted Answer

deoxyribose

Question 6

What did Chargaff discover while studying bases in the DNA of organisms?

Revolt · Accepted Answer

The ratios of thymine and adenine were similar, as were the ratios of guanine and cytosine.

Question 7

Proteins are made in ribosomes, but DNA is stored in the nucleus. How does RNA help in this process?

Revolt · Accepted Answer

RNA copies DNA and transports it to ribosomes for protein synthesis.

Question 8

Which of the following could be a nucleotide of RNA?

Revolt · Accepted Answer

ribose + phosphate group + uracil

Question 9

Which structural component is found in DNA but not in RNA?

Revolt · Accepted Answer

deoxyribose

Question 10

Which discovery is attributed to Phoebus Levene?

Revolt · Accepted Answer

identification of ribose and deoxyribose
