Answer:
The correct answer is option d) "Silencer".
Explanation:
Gene silencing is the regulation of a gene expression that results in avoiding the expression of a gene during a certain period of time. A silencer is a DNA sequence that produces gene silencing. In this example the researcher founds that a gene is not longer regulated in all cells and the gene is still transcribed and translated into protein. The mutation responsible of this it is likely to be occurring in a silencer, avoiding gene silencing of the studied gene in all cells.
Botulism can easily be prevented by boiling food prior to consumption.
<h3>What is Botulism?</h3>
Botulism may be defined as an imperative food poisoning that is provoked by botulinum toxin delivered in food by a bacterial species clostridium botulinum.
Clostridium botulinum inhibits the release of acetylcholine in the neuromuscular junction and causes defects in sensory perception through the central nervous system.
It can only be prevented by taking the proper boiled food prior to consumption.
The complete question is as follows:
- boiling food prior to consumption.
- administering antibiotics to patients.
- not eating canned food.
- filtering food.
- preventing fecal contamination of food.
Therefore, the correct option for this question is A, i.e. boiling food prior to consumption.

Ribosomal RNA (rRNA) associates with a set of proteins to form ribosomes. These complex structures, which physically move along an mRNA molecule, catalyze the assembly of amino acids into protein chains.
