A Diploid Cell Only Has Two Copies of Most Genes,but

Multiple Choice

A diploid cell only has two copies of most genes,but can make hundreds of copies of a protein from those genes per second because

A) the DNA can replicate during transcription, producing double-sided mRNA to accelerate the translation process.
B) multiple ribosomes can actively attach to the template DNA and conduct translation immediately after transcription.
C) multiple codons can encode for the same amino acid, allowing different versions of the protein to be made.
D) while transcription can repeat and make multiple mRNA copies of genes, and multiple ribosomes can translate the same mRNA.
E) multiple copies of the same mRNA can be produced with multiple promoter sequences to simultaneously initiate multiple ribosomes.
