Question

A gene for microtubule proteins is being made in a cell. How can mRNA represent an exact copy of that gene?

A) DNA polymerase make a copy of that gene that is inserted into the mRNA

B) RNA polymerase cuts out a section of the DNA

C) it is put together using base-paring rules

Answer 1

A is the answer for the question

Answer 2

Answer;

C) it is put together using base-paring rules

Explanation;

• Gene expression is the process by which genetic information carried by DNA are converted from genes via messenger RNA to proteins.
• mRNA is the molecules that links genes to proteins. The mRNA is formed through the process of transcription from a gene strand. The mRNA is then translated into protein by the joint action to transfer RNA and the ribosome.
• mRNA therefore, serves as a temporary copies of information found in the DNA. Thus, and mRNA represents an exact copy of the gene and it is put together using base pairing rules.
