DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
mRNA being made from DNA in the nucleus is the process of . . .
A
Translation
B
Replication
C
Transcription
D
Cell Division
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). DNA safely and stably stores genetic material in the nuclei of cells as a reference, or template.

Detailed explanation-2: -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.

Detailed explanation-3: -During transcription, the enzyme RNA polymerase (green) uses DNA as a template to produce a pre-mRNA transcript (pink). The pre-mRNA is processed to form a mature mRNA molecule that can be translated to build the protein molecule (polypeptide) encoded by the original gene.

Detailed explanation-4: -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-5: -Transcription. Messenger RNA (mRNA) synthesis using DNA as the template is called transcription. The mRNA carries genetic information from the DNA of the chromosomes in the nucleus to the surface of the ribosomes in the cytosol. It is synthesized as a single strand.
