Question

What does it mean to say that a gene is expressed?

a. A protein is used to make DNA.
b.DNA contains the information needed to make a protein
c.Lens cells make crystallin protein.
d.Information in DNA is used to make a protein.

Answer 1

Gene expression is the process of using a gene to produce RNA and proteins. It involves transcribing the information in DNA into mRNA, which is then translated into protein.

Step-by-step explanation:

Gene expression refers to the process of using a gene to produce RNA and proteins. When a gene is expressed, the information in the DNA is transcribed into mRNA, which is then translated into a protein. This process is essential for the proper functioning of cells, as different cell types only express the genes that code for the proteins they need.
