Assume that a base-pair substitution mutation converts a DNA triplet (AAT) to another DNA triplet (AAA). A second mutation now changes the AAA triplet to the GAA triplet. (UUA and CUU code for leucine and UUU codes for phenylalanine.) This second mutation is an example of a(n):

The answer is "intragenic suppressor".

Explanation:

In this question, the second mutation on the inside of a mutated gene, that leads to both a simple restoration. Its second mutations were its instance of even a mutation suppresser because it contributed to both the evident recovery of its original phenotype from its second mutation within such a gene.

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.

the answer is c.mitochondria. glad to .
