Answer:
The correct answer is option c. "frameshift mutations".
Explanation:
The reading frame of a gene is based on base-pair triplets, starting from the start codon until the ribosome encounters with the end codon. Base-pair additions and deletions are collectively referred to as frameshift mutations because they alter the reading frame of the gene. Base-pair additions and deletions break down the original sequence of the gene triplets, which alters the open reading frame and usually results in the production of non active proteins.
Answer:
Hypochlorhydria is a condition in which the quantity of stomach acids is reduced. When severe forms of hypochlorhydria arise, then it leads to a condition termed as Achlorhydria. The stomach stops producing hydrochloric acid at all in such a condition.
The effects of Achlorhydria would be devastating on the body. It will
- weaken or entirely stop the digestive process.
- impair the gastrointestinal system.
- stop the proper digestion of proteins.
- cause gastrointestinal infections to occur which would entirely damage the digestive system.
- lead to iron deficiency
