DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The process of making mRNA from DNA is called.
A
Replication
B
Transcription
C
Translation
D
Protein synthesis
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: -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-3: -Transcription has three stages: initiation, elongation, and termination. In eukaryotes, RNA molecules must be processed after transcription: they are spliced and have a 5’ cap and poly-A tail put on their ends. Transcription is controlled separately for each gene in your genome.

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.
