Which best describes how mRNA is produced in a cell?

A: mRNA is made by DNA, using RNA polymerase as a template.
B: mRNA is made by RNA polymerase, using DNA as a template.
C: mRNA is made by breaking apart DNA and reusing the pieces.
D:mRNA is made by duplicating RNA found in the necleus

Answer 1

I feel as if the answer is B. I hope this helps!

Answer 2

mRNA is made by RNA polymerase, using DNA as a template.

What is DNA?

• DNA stands for deoxyribonucleic acid and is a genetic material.
• DNA consists of nitrogenous bases, deoxyribose sugar and phosphate group.
• Nitrogenous base is of two types: purines and pyrimidines.
• Purines consists of Adenine and Guanine.
• Pyrimidines consists of Cytosine and Guanine.
• DNA undergo into transcription process to synthesis mRNA.

What is mRNA?

• mRNA stands for messenger ribonucleic acid.
• It is a single stranded molecule of RNA which corresponds to that of gene.
• The process of synthesis of mRNA from DNA by using RNA polymerase enzyme is called transcription.

Hence, the correct option is B: mRNA is made by RNA polymerase, using DNA as a template.
