a. mRNAs are made from genes.

Explanation:

A gene is a stretch of the DNA molecule and serves to specify the nucleotide sequence of an mRNA. Transcription is the process during which mRNA is synthesized by using the nucleotide sequence of a gene. The enzyme RNA polymerase copies the nucleotide sequence of the template DNA strand into the nucleotide sequence of mRNA. The process occurs in the nucleus in eukaryotes and the mature mRNA leaves the nucleus to enter the cytoplasm.

The mRNA joins ribosomes to synthesize proteins. The nucleotide sequence of mRNA serves as a template of the amino acid sequence of a protein. Therefore, a gene code for a protein through mRNA.
