There are different classes of mutation but the descriptions given here are specifically applied to cystic fibrosis, particularly referring to the CFTR (<span>Cystic fibrosis transmembrane conductance regulator) </span>gene.
<u>Mutation Classes</u>
Class I - Gene contains a stop signal that prevents CFTR from being made.
Class II - CFTR is made, but does not reach the cell membrane
Class III - CFTR is made and in the right place, but does not function normally
Class IV - Channel does not move substances efficiently or at all
Class V - <span>CFTR is made in smaller than normal quantities
(Source: </span>https://www.biologycorner.com/worksheets/case_study_cystic_fibrosis.html)
Given these different classes, the easiest one to correct would most likely be Class V, since in this type of mutation, the only problem or abnormality is the production of insufficient amounts of the needed CFTR.
The equation<span> for </span>photosynthesis<span> states that the combination of carbon dioxide, water, and light energy produces a carbohydrate (glucose) and oxygen. The chemical formula is 6CO2 + 6H2O + light energy = C6H12O6 + 6O2.</span>
