Anticodon - Correct answer-In the ribosome, what pairs with the codon?
peptide bond - Correct answer-In the ribosome, what is the name of the bond that links
one amino acid to the next?
uracil instead of thymine - Correct answer-Which nucleotide is different in RNA
compared to DNA?
purines and pyrimidines - Correct answer-List the two basic categories of nitrogenous
bases in nucleic acids.
False - Correct answer-T/F Uridine is a nucleotide in DNA.
False - Correct answer-T/F RNA is double stranded.
Introns - Correct answer-During mRNA maturation what is the name of the part of the
mRNA that is removed?
Free or Membrane Bound - Correct answer-There are two types of protein synthesis in
eukaryotic cells. These two types can be distinguished because the polyribosome is
either or .
Ribose - Correct answer-Which sugar is present in RNA?
Leading strand - Correct answer-Which strand is produced more rapidly?
T or thymidine - Correct answer-In DNA, what does the nucleotide labeled as A pair
with?
Nucleosome - Correct answer-The double helix of DNA is wrapped about 1¾ times
around which of these components?
RNA splicing - Correct answer-List one type of post-translational modification.
Nucleic acid to amino acid - Correct answer-Protein synthesis changes from the
language of to the language of .
- Correct answer-Draw the sugar in DNA and label the carbons as discussed in the
lecture. Then circle the carbon that is different in RNA.
Helicase - Correct answer-Which enzyme unwraps the double helix?
, 12 - Correct answer-Assume that you have a eukaryotic cell with three chromosomes
within it. How many 5' ends would there be?
Primase - Correct answer-For DNA Polymerase III to work which of these components
has to act first?
Okazaki fragments - Correct answer-During DNA replication in the lagging strand there
is production of this component?
True - Correct answer-T/F During DNA replication is greatly reduced by enzymes that
proof read the newly replicated DNA.
initiation, elongation, termination - Correct answer-RNA synthesis, also called RNA
transcription occurs in three phases. List them from beginning to end in order.
Primase - Correct answer-Which enzyme is used first to permit DNA polymerase III to
begin replicating the 3' strand?
True - Correct answer-T/F The genetic code for the conversion of mRNA codons to
proteins has redundancy.
AUG - Correct answer-In eukaryotic cells the start codon for protein synthesis is .
3 - Correct answer-How many "stop" codons exist?
2 - Correct answer-How many hydrogen bonds are there between an A and its paired
nucleotide?
False - Correct answer-T/F The DNA polymerase that replicates the parental strand of
DNA reads the parental DNA from 5' to 3" and makes a new DNA strand from 3' to 5'.
True - Correct answer-T/F Replication of DNA is semi-conservative.
False - Correct answer-T/F Strands of the backbone of DNA are parallel?
True - Correct answer-T/F In the lagging stand, the DNA is read from the parental
DNA's 3' to 5' end.
True - Correct answer-T/F DNA replication in eukaryotes is sped up by multiple origins
of replication.
