which of the following statements is/are correct?
a. Ribosomes are made up by many different proteins.
b. An individual ribosome can make only one type of protein.
c. All mRNAs fold into particular 3D structures that are required for their translation.
d.The large and small subunits of an indiv...
Nucleic acids and proteins are both polymers made of a set of monomers. Complete
the following analogy: _______ are to nucleotides as side chains are to amino acids.
A. Ribose/deoxyribose sugars
B. Phosphate ions
C. Nitrogenous Bases
D. Nucleosides
E. Hydroxyl Groups
✓✓~ C. Nitrogenous Bases
This is what differentiates the different nucleotides, A vs T vs C vs G
Which of the following factors contributes to the strength of the intermolecular
interaction between two DNA strands in a double helix?
A. Strong hydrogen bonds between the sugar and phosphate groups
B. Its double-helix shape
C. The direct bonding of the base to the phosphate molecule
D. Hydrogen bonds between purines and pyrimidines
,E. Phosphodiester bonds between the nitrogenous bases
✓✓~ D. Hydrogen bonds between purines and pyrimidines
This is where the hydrogen bond is to form the double helix
Purines
A. are the larger of the two types of nitrogenous bases found in DNA.
B. that are found in DNA are adenine and thymine.
C. that are found in DNA are cytosine and thymine.
D. are nitrogenous bases that form DNA base pairs with each other
E. none of the above.
✓✓~ A, C
Purines have a double ring and the C and G have them because they can make 3
hydrogen bonds so they are stronger
In trying to determine whether DNA or protein is the genetic material, Hershey and
Chase made use of which of the following facts?
a.DNA contains sulfur, whereas protein does not.
b. DNA contains phosphorus, whereas protein does not.
c. DNA contains nitrogen, whereas protein does not.
d. DNA contains purines, whereas protein includes pyrimidines.
e. RNA includes ribose, whereas DNA includes deoxyribose sugars.
, ✓✓~ b. DNA contains phosphorus, whereas protein does not.
Phosphate group binds to the sugar
If a short sequence of DNA is 5' AATTGCCGT 3', its complement is
a. 3' TGCCGTTAA 5'.
b. 3' AATTGCCGT 5'.
c. 5' TTAACGGCA 3'.
d. 5' ACGGCAATT 3'.
✓✓~ d. 5' ACGGCAATT 3'.
Choose the one best answer. What is it about nucleic acids that makes copying
genetic information straightforward?
a. Hydrogen bonds are easily broken
b. The binding of bases to one another is specific.
c. The sequence of bases encodes information.
d. The shape of the molecule is determined by the information it contains.
e. NA; I don't know or prefer not to answer.
✓✓~ b. The binding of bases to one another is specific.
