In a skin cell which of the following changes may lead to skincancer? a) a change in a single nucleotide in a DNA molecule b) a change in a single nucleotide in an mRNA molecule c) a change in multiple amino acids of a single proteinmolecule d) a change in the conformation of an enzyme molecule e) a change in the number of enzyme molecules present in thecell In a skin cell which of the following changes may lead to skincancer? a) a change in a single nucleotide in a DNA molecule b) a change in a single nucleotide in an mRNA molecule c) a change in multiple amino acids of a single proteinmolecule d) a change in the conformation of an enzyme molecule e) a change in the number of enzyme molecules present in thecell

Explanation / Answer

The answer is most likely A. mRNA  is constantly made and degraded as well as proofread during transcrition and translation. As for proteins (which include enzymes), a change that makes them useless or nable to function will be degraded. DNA that gets mutated and isn't fixed usually leads to cancer or apoptosis. I hope that helps.
