Question 1

Which represents a strand of RNA bases?

Revolt · Accepted Answer

UGGCUCGAA

Question 2

Which base is found only in RNA?

Revolt · Accepted Answer

uracil

Question 3

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

Revolt · Accepted Answer

Because uracil is unique to RNA.

Question 4

Which discovery is attributed to Phoebus Levene?

Revolt · Accepted Answer

identification of ribose and deoxyribose

Question 5

Which structural characteristic is seen in RNA but not in DNA?

Revolt · Accepted Answer

a single strand

Question 6

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 7

DNA is a nucleic acid polymer composed of which repeating structural unit?

Revolt · Accepted Answer

nucleotides

Question 8

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 9

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

Revolt · Accepted Answer

deoxyribose

Question 10

What is the role of RNA?

Revolt · Accepted Answer

to move information from the nucleus to the ribosomes for protein synthesis
