Question

based on all the information provided in figures 1 and 2, which explanation best fits the gene mutation data? (1 point)

a change in dna coding for the ribosome blocks translation, so little protein is produced and the enzyme is inactive.

heat stress damages dna, lowering transcription and protein levels.

low nutrient levels reduce transcription, which lowers protein and enzyme activity.

extra mrna is degraded before it leaves the nucleus, preventing translation.

Explanation:

Gene mutations can disrupt normal biological processes related to protein - production. A change in DNA coding for the ribosome can directly affect translation as ribosomes are key for protein synthesis. If translation is blocked, little protein is produced and enzymes (which are often proteins) can be inactive. Heat stress, low nutrient levels, and mRNA degradation are not directly related to gene mutations in the context of ribosome - coding DNA changes.

Answer:

A. A change in DNA coding for the ribosome blocks translation, so little protein is produced and the enzyme is inactive.
