the answer is C.
Plants use atmospheric CO2 through photosynthesis
It is a very long sequence, written in code, that needs to be transcribed and translated before a cell can make the proteins that are essential for life. Any sort of changes in the DNA sequence can lead to changes in those proteins, and, in turn, they can translate into changes in the traits those proteins control.
It has made insulin cheaper and more readily available most likely improved the lives of diabetics
<u>Explanation:</u>
Ineffectual composition of the hormone recognized as insulin leads to an issue termed diabetes. Insulin permits the body's cells to consume glucose, which they utilize as food. Demand to discover a method to generate huge amounts of insulin economically raised when the number of crises of diabetes extended to rise. Genetic engineering procedures provide microorganisms for this plan.
Diabetes victims have to infuse insulin to regulate their blood sugar levels. A variety of insulin from yeast and bacteria like E. coli has been designed by Genetic engineering. This genetically mutated insulin, ‘Humulin’ was authorized for human application in 1982.
