Answer: I believe it is A. DNA polymerase checking the DNA
The RNA synthesis or ADN transcription occurs in the nucleus and requires:
- DNA strand to act as a template.
- Enzymes, specially the RNA-polymerase.
- Ribonucleotides of Adenine, Guanine, Cytosine and Uracil.
This consist of three maturation of the 3'-->5' direction while the sense of RNA synthesis is 5'-->3'.
This is fulfilled because the enzyme selects the ribonucleotide whose base is complementary to the DNA chain that acts as a template, and binds it by means of a nucleotide bond, releasing a phosphate group.
I believe it's C, made in light-dependent reactions and used in light-independent reactions.
It’s D, other answers don’t make sense
Minerals are composed of multiple elements and rocks are actually made up of minerals. Take quartz for example, it's a mineral that's made up of silicon and oxygen. If we then look at the igneous rock that is referred to as granite, we'll see quartz (the main one), mica(s), and feldspar.
So your answer is B. :)
