Answer 1

Nucleases are enzymes that break the phosphodiester bonds between nucleotides in nucleic acids. They control the amount of a specific protein product within a cell by degrading excessive or unnecessary RNA, thus controlling its quantity and the count of protein synthesized. Nucleases are also involved in post-transcriptional modifications where they refine the mRNA for better translation into the protein product, therefore affecting the resultant protein amounts. They further eliminate harmful DNA helping cut down adverse effects on RNA and subsequently, protein synthesis.

Answer 2

Nucleases are enzymes that cleave the phosphodiester bonds between the nucleotide subunits of nucleic acids. These enzymes are essential for many functions such as DNA repair, replication, and recombination. They occur naturally in cells and have a crucial part to play in controlling the amount of a specific protein product present within the cell. Nucleases achieve this control in a couple of ways. First, they degrade unnecessary or excessive RNA, controlling its quantity in the cell and thus the amount of protein synthesized. This happens because messenger RNA (mRNA) is what carries the information from the DNA for protein synthesis ; hence, controlling the mRNA amounts directly influences protein levels. Furthermore, nucleases are used in post-transcriptional modifications, where the mRNA is fine-tuned for accurate and efficient protein production. This step can involve singling out defective mRNA for degradation or trimming mRNA for better translation into the protein product. Nucleases thus ensure that the gene expression needed for protein synthesis is tightly controlled and properly regulated not just at transcription level, but through the life cycle of the mRNA molecule up to translation, contributing substantially to the end quantity of the protein liking a lever for altering the protein's eventual presence in the cell. It’s also important to note that In relation to protein presence, nucleases help pave way for the removal of harmful DNA. This safeguards both the subsequent RNA and finally, protein synthesis. To answer a question like this, one typically does a thorough internet research keenly focused on nucleases’ function description typically available in biology textbooks, learning resources, research articles or known source like the National Center for Biotechnology Information.
