Answer:
A) A single base pair change.
Explanation:
Point mutation is a change in a single base pair of a nucleotide. This comes as a results of mistakes made during DNA replication, induced by ultravoilet radiations, extreme heat and X-rays. There are three types of point or substitution mutations; change, deletion and insertion. The nucleotide bases are either mistakenly inserted, changed or deleted, thus changing the resulting protein or amino acid being coded for.
Answer:
the concentration of misfolded proteins would be higher than normal.
Explanation:
Chaperones proteins are required for the correct protein folding of proteins. These proteins were first discovered in bacteria. The level of chaperones is increased under thermic stress conditions, it is for that reason that they are also known as heat shock proteins (Hsp). For example, Hsp70 is a chaperon protein constitutively expressed under stress conditions that is involved in the folding of protein precursors and the refolding of misfolded proteins. In humans, Hsp70 is encoded by the HSPA1A gene, and its increased expression level is related to different health problems including neurodegenerative diseases, cerebral ischemia and epilepsy.
