Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Transcription is the process of:
A
Making DNA
B
Making mRNA from DNA
C
“Unzipping” the molecule of DNA
D
Assembling a protein from RNA
Explanation: 

Detailed explanation-1: -The process of making mRNA from DNA is called transcription, and it occurs in the nucleus. The mRNA directs the synthesis of proteins, which occurs in the cytoplasm. mRNA formed in the nucleus is transported out of the nucleus and into the cytoplasm where it attaches to the ribosomes.

Detailed explanation-2: -Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA).

Detailed explanation-3: -In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription.

Detailed explanation-4: -In prokaryotic cells, transcription (DNA to mRNA) and translation (mRNA to protein) are so closely linked that translation usually begins before transcription is complete.
