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.
