hope that helps :)
Answer:RNA polymerase – makes a molecule of RNA from an RNA template
Explanation: RNA polymerase is an enzyme that catalyzes the copying of a DNA sequence into an RNA sequence during transcription. RNA polymerase uses a DNA template for the synthesis of an RNA strand. RNA polymerase is also called DNA-dependent RNA polymerase. During transcription, DNA helicase unwinds the double helix of the DNA while the RNA polymerase catalyzes the synthesis of an RNA strand from the DNA.
C: carbon and oxygen cycles are the most closely related in their role in sustaining life because they both include processes of exchanging themselves among different parts of the earth. E.g. they both process through the ground, in the air, etc.
