A claim states, "Finding two protein isoforms proves that two separate genes are involved." Which observation would most directly challenge the claim?
A
Both protein isoforms contain amino acids, so neither can be related to RNA processing.
B
Both protein isoforms are translated from mature mRNAs derived from the same primary transcript.
C
The cell contains chromosomes, so every protein must come from a separate chromosome.
D
The mature mRNAs have caps, so their exon combinations cannot be compared.
