Question 22 • Biology

Which discovery is attributed to Phoebus Levene?

Answer
A
construction of an accurate DNA model
B
extraction and observation of DNA
C
identification of ribose and deoxyribose
D
recognition of RNA as DNA’s messenger

Explanation

Phoebus Levene identified the sugars in nucleic acids: ribose in RNA and deoxyribose in DNA. Watson and Crick are associated with the accurate DNA model, while the discovery of DNA and recognition of messenger RNA are associated with other scientists. Therefore, the correct choice is identification of ribose and deoxyribose.
