Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is transcription?
A
This process creates proteins
B
This process occurs in the cytoplasm
C
This process by which DNA is coded in RNA, occurs in the nucleus and involves both DNA and RNA, this process creates RNA
Explanation: 

Detailed explanation-1: -Transcription is the process in which a gene’s DNA sequence is copied (transcribed) to make an RNA molecule. RNA polymerase is the main transcription enzyme. Transcription begins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins).

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 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-4: -The process of Transcription takes place in the cytoplasm in prokaryotes and in nucleus in eukaryotes. It uses DNA as a template to make an RNA (mRNA) molecule. During transcription, a strand of mRNA is made that is complementary to a strand of DNA .
