If there was a dramatic increase in skeletal muscle cell damage and apoptosis, what would you expect to happen to levels of myog
leva [86]

If there was a dramatic increase in skeletal muscle cell damage and apoptosis, I would not expect a change in blood myoglobin and CK levels, because these markers are linked to cardiac muscle damage.

<h3>What does high CK-MB mean?</h3>

Elevated CKMB can be a sign of cardiac (heart muscle) damage or chronic kidney failure. At the onset of acute symptoms, after cardiac peaks, CKMB values ​​are elevated after 3-6 peaks after 12-24 hours between 12-24 hours, values ​​at 24-48-48.

With this information, we can conclude that if there was a dramatic increase in skeletal muscle cell damage and apoptosis, we would not expect a change in blood myoglobin and CK levels, because these markers are linked to cardiac muscle damage.

According to google

So the ribosome moves along way and many tRNA molecule transport the correct amino acid to make the correct sequence which is to be formed and only stops when mRNA shows 'STOP' codon. So there is a chain of polypeptide which is synthesised by copying the DNA and this is how proteins are made.

and for clarification t-RNA is transfer RNA and m-RNA is messenger RNA
