DNA Functions as a Sort of Recipe for the Proteins

Question 37

Multiple Choice

DNA functions as a sort of recipe for the proteins that make an organism what it is and make it work. It doesn't make proteins directly but directs a series of steps that result in proteins. Which sequence below correctly follows how this works?


A) DNA is translated into messenger RNA.
Transfer RNA produces the amino acids coded by the mRNA.
Ribosomal RNA holds together the mRNA and tRNA to connect the amino acids together. The amino acids are transcribed into the proteins specified by the original DNA.
B) DNA is transcribed into messenger RNA.
Transfer RNA produces the amino acids coded by the mRNA.
Ribosomal RNA holds together the mRNA and tRNA to connect the amino acids together. The amino acids are translated into the proteins specified by the original DNA.
C) DNA is transcribed by ribosomes into transfer RNA.
Transfer RNA produces the amino acids coded by the DNA.
Messenger RNA then holds together the amino acids. The amino acids are translated into proteins as specified by the original DNA.
D) DNA makes proteins directly by assembling pieces of messenger RNA together into amino acids.
E) DNA doesn't actually do anything directly, but RNA produces amino acids from protein codes.
