DNA polymerase has multiple mechanisms for editing and error correction whereas the capacity for error correction in RNA polymerases seems to be quite limited. However, like DNA mutation, an RNA polymerase error in transcription can cause production of a mutated protein. The limited error correction of RNA polymerase seems to be inconsistent with the potential serious consequence of producing a protein with an altered amino acid sequence. Select three reasons that explain why error correction is not as necessary in RNA polymerases as it is in DNA polymerases.

The given question is incomplete as the option are not provided however, the correct options are as follows:

Defective proteins are often degraded quickly, making their effects temporary.

Single amino acid substitutions caused by errors in mRNA transcription would not affect protein function.

Unlike DNA mutations, mRNA transcripts have short half-lives and are not inherited across many generations.

Degradation of defective proteins activates mRNA repair pathways RNA polymerases synthesize many transcripts per gene, so only a small fraction of RNA transcripts would have errors.

ch mRNA molecule is only translated once and then degraded

The correct answer is - statements 1, 3, and 4.

Explanation:

DNA polymerase is the enzyme that is responsible for the production of the new DNA molecule and any mutation in this enzyme that will inhibit the DNA repair process which affects future generations.

RNA polymerase is an enzyme that is responsible for the transcription of DNA to mRNA and any error-prone mRNAs have chances of degradation. Error in DNA replication is from generation to generation as it is inherited

The process of transcription is quick.

true, generally referred to as invasive species given that they have no natural predators in new environment

emerald ash borer

the emerald ash borer is a green buprestid or jewel beetle native to north-eastern asia that feeds on ash species. females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years. hope this !
