During the process of cell division, it is necessary to make a duplicate copy of DNA for any new cells produced. First, the template strand of DNA is unwound by breaking the hydrogen bonds between the complementary strands. Next an RNA primer acts as an anchor for the new DNA strand to form. Last, matching nucleotides are connected to the growing DNA chain and gaps between DNA fragments are sealed together. All of these complex processes require enzymes in order to progress. All of the following enzymes are necessary for successful DNA replication EXCEPT
A. Helicase
B. DNA Polymerase
C. Ligase
D. RNA Polymerase

D. RNA Polymerase

Explanation:

The enzyme RNA Polymerase is present during transcription, which is the process where DNA is transcribed into RNA to be later translated and give a protein. During transcription, RNA Polymerase synthesizes DNA using a strand of DNA as a template. In other words, it transcribes the DNA into RNA.

During replication, one strand of the DNA is replicated using a DNA strand as a template. The result is a new cell with the same information as the original cell. In this process, there is not RNA synthesis. If there is no RNA synthesis, there is no RNA polymerase.

i am positive it is c. condensing but i may be wrong

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.
