A student proposes that cap loss reduces protein output only because it shortens the mRNA. Which observation would most clearly refute that proposal?
A
The uncapped mRNA is shorter and also has lower protein output.
B
The capped mRNA is longer because its poly-A tail is made of amino acids.
C
The uncapped mRNA is full length but has lower ribosome loading than the capped full-length mRNA.
D
The uncapped mRNA is found only in DNA sequencing reads.
