Insulin and glucagon are the hormones that cause blood glucose (blood sugar) preserved in a narrow range. The pancreas serves as the central part of this process. Secreted by the pancreas are both insulin and glucagon. Determined by the production of insulin and glucagon, people can find out whether someone may have diabetes, <span> hypoglycemia, low blood pressure, etc. Insulin or glucose can be prescribed to victims of those listed issues, it is mostly used to balance out the level of glucagon and insulin to try to stop the problem.</span>
Answer: The correct answer is B) Frameshift mutation.
The given mRNA sequence is GGU-GCU-CCU-AUU. When a nucleotide is added at the fourth location in the chain, it entirely changes the frame from the insertion of the nucleotide till the end of the gene sequence. This is called a frameshift mutation.
This is because after adding a nucleotide, a new frame is generated that will code for different amino acids and therefore a different protein will be synthesized.
On the contrary, chromosomal mutation is an abnormality in the chromosome ( in terms of number or structure) whereas substitution mutation is the one, which exchanges one base with another. Deletion of base also results in the frame-shift mutation.

B. DNA is excised from one location to another within a DNA molecule
Answer: It is repressible because wild-type transcription is repressed in the presence of Compound B
Explanation:
An operon is a segment of DNA containing adjacent genes including structural genes, an operator gene, and a regulatory gene. In other words you can say it is the functional unit of transcription and gene regulations.
There are 3 types of operons
1) inducible operon- this system is a regulated unit of genetic material which is switched on in response to the presence of a chemical. Means that transcription is turned on when a specific molecule is present.
2) Repressible Operon: in this system, transcription stops when the repressor gene product is activated and the sufficient amounts of the gene product inhibit further transcription.
The third is Constitutive Operon: in this case, the amount of gene product is constant.
