Question

while researching a topic, a student has taken the following notes:severo ochoa discovered the enzyme pnpase in 1955.pnpase is involved in both the creation and degradation of mrna.ochoa incorrectly hypothesized that pnpase provides the genetic blueprints for mrna.the discovery of pnpase proved critical to deciphering the human genetic code.deciphering the genetic code has led to a better understanding of how genetic variations affect human health.the student wants to emphasize the significance of ochoas discovery. which choice most effectively uses relevant information from the notes to accomplish this goal?a ochoas 1955 discovery of pnpase proved critical to deciphering the human genetic code, leading to a better understanding of how genetic variations affect human health.b ochoa first discovered pnpase, an enzyme that he hypothesized contained the genetic blueprints for mrna, in 1955.c in 1955, ochoa discovered the pnpase enzyme, which is involved in both the creation and degradation of mrna.d though his discovery of pnpase was critical to deciphering the human genetic code, ochoa incorrectly hypothesized that the enzyme was the source of mrnas

Explanation:

Option A connects Ochoa's discovery of PNPase to the significant outcome of deciphering the human genetic code and its impact on understanding genetic - variations and human health, which emphasizes the significance of the discovery. Option B just states the discovery and the hypothesis without highlighting significance. Option C only mentions the discovery and the enzyme's function in mRNA creation and degradation. Option D mentions the significance but also focuses on the incorrect hypothesis, diluting the emphasis on the discovery's significance.

Answer:

A. Ochoa's 1955 discovery of PNPase proved critical to deciphering the human genetic code, leading to a better understanding of how genetic variations affect human health.
