Hope this help.
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.
The monosaccharides important in food and health are glucose<span> (sometimes called dextrose), </span>fructose<span>, and </span>galactose. The disaccharides are sucrose (glucose<span> +</span>fructose), lactose (glucose<span> + </span>galactose), and maltose (glucose<span> + </span>glucose<span>).</span>
Answer:
Aloes adapt to this by using their tissue to store large volumes of water. Aloe vera has thick and fleshy leaves, which are enlarged to accommodate the aqueous tissue. ... Carbohydrates synthesized in excess of that needed for energy are transported by the phloem to the cells in the leaf pulp.

Nucleus is the main component of the cell and carries out the vital processes of the cell.
- For learning about its structure, a nucleus diagram is quite helpful. Important components of its structure include.
- One feature of the nucleus that distinguishes eukaryotic cells from prokaryotic ones is the nuclear membrane.
- Additionally, it has a double-layer structure. It also has phospholipids in it.
- The nuclear envelope, nucleoplasm, or nucleus sap, nuclear matrix, chromatin, and nucleolus are some of the several structures that make up the nucleus.
- The nuclear membrane, also referred to as the nuclear envelope, creates an envelope-like structure surrounding the nuclear contents.
