Question

Which discovery is attributed to Phoebus Levene?

Answer 1

Answer options:

• extraction and observation of DNA
• identification of ribose and deoxyribose
• recognition of RNA as DNA’s messenger
• construction of an accurate DNA model

Answer:

• identification of ribose and deoxyribose

Explanation:

Phoebus Levene was an American biochemist who studied the structure of DNA and RNA. He was able to isolate the sugars (ribose and deoxyribose) from the nucleic acids, which are an important part of their structure.

He also determined how the nucleic acid components combine to form the nucleotides, the basic building blocks of nucleic acids, and how the nucleotides combine in chains to form the polymer.

Answer 2

Answer:

B

Explanation:

identification of ribose and deoxyribose
