Answer:
C.
Explanation:
In mRNA, there isn't a Thymine nitrogen base. There is a "new" nitrogen base called Uracil, which takes its place. So in transcription, A=U and C=G.
An oxidation-reduction<span> (</span>redox<span>) </span>reaction<span> is a type of chemical </span>reaction<span> that involves a transfer of electrons between two species. An </span>oxidation-reduction reaction<span> is any chemical </span>reaction<span> in which the </span>oxidation<span> number of a molecule, atom, or ion changes by gaining or losing an electron.</span>
Gradualism and punctuated equilibrium are two ways in which evolution of a species can occur. Gradualism is selection and variation that happens more gradually; over a short period of time it is hard to notice
I think the correct answer from the choices listed above is option 1. The statement that would describe this insertion would be that a new base had been inserted. As you can see, G is inserted between G and C. Hope this answers the question. Have a nice day.
