DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which process is used to make mRNA from the DNA in the nucleus?
A
transcription
B
translation
C
replication
Explanation: 

Detailed explanation-1: -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-2: -During transcription, a piece of DNA that codes for a specific gene is copied into messenger RNA (mRNA) in the nucleus of the cell. The mRNA then carries the genetic information from the DNA to the cytoplasm, where translation occurs.

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: -Formation of mRNA from DNA is called as transcription. Transcription is when RNA is made from DNA. During transcription, RNA polymerase makes a copy of a gene from the DNA to mRNA as needed.
