Textbook Question
Chapter 9, Problem 2PDQ
Review the Chapter Concepts list on p. 160. Most center on DNA and RNA and their role of serving as the genetic material. Write a short essay that contrasts these molecules, including a comparison of advantages conferred by their structure that each of them has over the other in serving in this role.

A) Protein 1 and protein 2 will function exactly the same.
B) Protein 1 will be shorter than protein 2, so they will not function the same.
C) Protein 2 will be shorter than protein 1, so they will not function the same.
D) Protein 2 has a different sequence, so it will function…
Which of the following describe how the order of nucleotide bases along a gene in the DNA ultimately determines the primary structure of a protein and how the primary structure ultimately determines the three-dimensional shape and function of the protein coded for by that gene.
A
Certain amino acids in a protein interact with other amino acids in that same protein and so the order of amino acids ultimately determines the 3-dimensional tertiary structure of that protein.
B
The order of nucleotide bases along the DNA is transcribed into complementary tRNA which is translated into the correct amino acid sequence for the protein by mRNA.
C
The order of nucleotide bases along a gene determines the order of amino acids in the resulting protein. The order of amino acids in the protein is called its secondary structure.
Discuss the structural significance of complementarity in DNAand in RNA.
