B)tRNA
C)amino acids
D)ribosomes

Question

Quizplus · Accepted Answer

In protein synthesis, the genetic code of DNA is transcribed into messenger RNA (mRNA) by the enzyme RNA polymerase. The mRNA then travels to the ribosomes where it is translated into a sequence of amino acids, the building blocks of proteins. tRNA (transfer RNA) carries the correct amino acid to the ribosome, where it is added to the growing protein chain. While ribosomes are essential for the process, they do not copy the genetic code from DNA.
