Cells Have Only Two Copies of Most Genes,but Can Make

Cells have only two copies of most genes,but can make hundreds of copies of a protein from those genes per second,because

A) during translation multiple DNA codons can encode the same amino acid.
B) during translation multiple copies of the same mRNA can be produced from one gene.
C) during translation DNA can replicate making more copies of the gene.
D) during translation proteins can replicate.
E) during translation multiple ribosomes can bind to the same mRNA simultaneously.
