Answer:
c) It introduces a premature stop codon into the mRNA
Explanation:
Nonsense mutation is a type of point mutation (single nucleotide base is changed) which leads to premature stop codon. Stop codons are also called nonsense codons and that is way this type of mutation is called nonsense mutation. As a consequence, synthesized protein is incomplete and shorter than it should be (truncated protein), usually nonfunctional.
Answer: Increased concentration of glucose in leaf cells
Explanation:
Based off the flowchart, the process that it's describing is photosynthesis because during this process sunlight and CO2 are taken in by a plant to produce glucose. If we are exposed to sunlight and are increasing the use of CO2, then there must be a higher concentration of glucose in the leaf cells. Glucose is a product of photosynthesis.
<span>The gene sequence containing an operator, promoter and repressor is known as an operon. These genes are called as structural genes. the operon is regulated by the presence/absence of the inducer such as glucose/lactose. It may also be a constitutive operon, which works all the time.</span>
