Question

The molecular pathway that plays the biggest role in determining cellular phenotype is:

A) DNA replication
B) Transcription
C) Protein degradation
D) Translation
E) Recombination

Answer 1

Translation is the molecular pathway that plays the biggest role in determining cellular phenotype.

Step-by-step explanation:

The molecular pathway that plays the biggest role in determining cellular phenotype is D) Translation.

Translation is the process in which a particular segment of DNA is copied into RNA (mRNA) by the enzyme RNA polymerase, and then the mRNA is used as a template to synthesize proteins.

Proteins are responsible for carrying out most of the cell's functions and determine the cell's phenotype.
