DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
DNA polymerase and RNA polymerase are similar in that they
A
are both enzymes
B
both are involved in making new polymers
C
both can be found doing work in the cell nucleus
D
all of these things are true
Explanation: 

Detailed explanation-1: -RNA Polymerase vs. DNA Polymerase. Both DNA polymerase and RNA polymerase share the same end goal: synthesizing nucleic acid in the cell. However, DNA polymerase produces double stranded DNA, whereas RNA polymerase produces single stranded RNA.

Detailed explanation-2: -DNA Polymerase synthesizes double-stranded DNA molecules, while RNA Polymerase synthesizes single-stranded RNA molecules. DNA Polymerase uses deoxyribonucleotides to form a new double-stranded DNA molecule, while RNA Polymerase uses ribonucleotides to form a single-stranded RNA molecule.

Detailed explanation-3: -In DNA, Adenine, Guanine, Cytosine, and Thymine are observed. Whereas in RNA, Adenine, Guanine, Cytosine, and Uracil are observed. In RNA, Thymine is replaced by Uracil. Hence, Adenine, Guanine, and Cytosine are common to both DNA and RNA.

Detailed explanation-4: -The main difference between DNA and RNA polymerase is that DNA polymerase produces a double-stranded DNA molecule during polymerization whereas RNA polymerase produces a single-stranded RNA molecule during transcription.
