Answer:
See the answer below
Explanation:
Both transcription and DNA replication produce nucleic acids which are polymers of (C, G, A, and T or U). Both processes depend on an enzyme which adds one nucleotide at a time.
To determine which nucleotide is added next, both transcription and DNA replication use the nucleotide sequence in a template DNA strand and the base pairing rules.
Transcription is a process through which RNA is synthesized using a DNA template. An enzyme known as RNA polymerase adds nucleotide bases to grow the RNA strand.
Replication is a process during which DNA makes a copy of itself. The double helix unwinds and each strand is used as a template to make a new strand. An enzyme known as DNA polymerase adds nucleotide bases to grow the new strands.
In both transcription and replication process, the nucleotide sequence of the template DNA strand determines the which nucleotide will be added to the new RNA and DNA strands being synthesized according to the base pairing rule. Purine bases always pair with pyrimidine bases and more specifically, cytosine always pair with guanine while adenine always pair with thymine (uracil in RNA).
