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
Answer:
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.
Answer:
B. The amount of unbound cyclin E is lowest as the cell enters S.
Explanation:
The reproduction of the cell is a cycle that it regulates by itself, depending the demand of a certain cell.
In the case of the mitosis, in Each change from G1 to S to G2 to M is regulated by some proteins like the cyclin.
In the case of the cdK2 is ncessary to pass the control point to pass from the stage G1 to the stage S.
Another characteristic of the cyclins, is that these proteins are synthetized and degraded constantly during the hole process.

Damage to cell membrane can also lead to leakage of important cell constituents required for various metabolism of the cell. There can also be imbalance of electrolyte concentration in the cell which could lead to damage of proteins and organelles of the cell.
