If a reading frame shift occurs during translation of an mRNA transcript, what is the MOST likely outcome?
The new amino acid chain will encode a protein with a distinct biological function.
The translation machinery will recognize the error and return back to the original reading frame.
The amino acid chain will be terminated by a stop codon before it can form a full length protein.
The mRNA transcript will be degraded.
It increases the chances of another reading frame shift, leading to translation machinery "slippage".
