Frameshift mutation is a type of genetic mutation wherein a change in sequence and order is caused, which is not by altering three nucleotides. Examples of this are insertions of bases or deletions of bases. The correct answer is A since A base or adenine is deleted causing a different reading frame.

<span>The correct answer is A) AGTCG.</span> The frameshift mutations are mutations that include insertions and deletions which, as a consequence, change the number of nucleotides in a DNA sequence that is not divisible by three. Because of the triplet nature of gene expression by codons the reading frame is altered, resulting in a completely different translation from the original. <span>In this case, deletion of the A (adenine) nucleotide occurred.</span>

<span>The protons want to diffuse into the mitochondrial matrix and they do this by going through the ATP synthase protein which resembles a water turbine. As the protons move through the ATP synthase, ATP is produced. In essence the energy from H+ wanting to diffuse through the inner mitochondrial membrane is converted to energy in the form of ATP</span>
