Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The process in which an RNA polymerase molecule assembles a mRNA molecule whose nucleotide sequence is complementary to the DNA sequence is called
A
gene amplification
B
translation
C
transcription
D
PCR
Explanation: 

Detailed explanation-1: -Transcription is the first step in decoding a cell’s genetic information. During transcription, enzymes called RNA polymerases build RNA molecules that are complementary to a portion of one strand of the DNA double helix (Figure 3).

Detailed explanation-2: -During transcription, the nucleotide sequence of the DNA strand that is being coded is ATACG, then the nucleotide sequence in the mRNA would be UAUGC.

Detailed explanation-3: -Translation is the process of synthesis of protein from RNA. In translation, messenger RNA (mRNA) produced by transcription is decoded by the ribosome to produce a specific amino acid chain, or polypeptide, that will later fold into an active protein.
