Download Identify which nucleic acid (DNA or RNA) contains each of the

Problem 1 Components of Nucleic Acids
Problem 2 Condensation of the Components
Provide the products for each of the following condensation reactions:
a.
b.
Problem 3 Nucleotides
Identify which nucleic acid (DNA or RNA) contains each of the following
nucleotides and state the components of each nucleotide:
a.
deoxyguanosine 5′-monophosphate (dGMP)
b.
adenosine 5′-monophosphate (AMP)
Problem 4 Bonding of Nucleotides
Draw the RNA dinucleotide (two nucleotides joined by a phosphodiester) formed if
two adenosine monophosphates undergo a condensation reaction. Label the 5′ and
3′ ends of your structure. Identify the phosphodiester bond.
Problem 5 Sequence Abbreviation
Provide an abbreviation for the following nucleic acid sequence:
Problem 6 Complementary Base Pairs
Write the base sequence and indicate the 3′ and 5′ ends of the complementary
strand for a segment of DNA with the base sequence 5′ ACGATCT3′ .
Problem 7 Transcription
The sequence of bases in a DNA template strand is 5′CGATCA3′. What is the
corresponding mRNA that is produced from this DNA?
Problem 8 Codons
What is the sequence of amino acids coded by the following codons in mRNA?
5′ GUC|AGC|CCA 3′
Problem 9 Translation
What order of amino acids would you expect in a peptide made from the following
mRNA sequence?
5′ UCA|AAA|GCC|CUU| 3′
Problem 10 Mutations
A mRNA has the sequence of codons 5′ CCC|AGA|GCC 3′ . If a base substitution
in the DNA changes the mRNA codon of AGA to GGA, how is the amino acid
sequence affected in the resulting protein? Can you predict whether this might have
an effect on the protein function?
Problem 11 Viruses
Why are viruses unable to replicate on their own?
Problem 12 Recombinant DNA Technology
Describe how a gene from one organism can be incorporated into a second
organism using recombinant DNA technology.
