DNA polymerase I _________ whereas DNA polymerase III
________.
a) replaces RNA nucleotides in the primer with DNA
nucleotides; adds the next nucleotide to the growing strands
b) proofreads newly made DNA to find errors; replaces RNA
nucleotides in the primer
c) adds RNA nucleotides to the growing strands that are
complementary to the parent strand; proofreads newly made DNA to
find errors
d) unwinds the DNA in order for DNA polymerase II to access
the DNA; adds the next nucleotide to the growing strand
What is a telomere?
a) the protein that holds two sister
chromatids together
b) The mechanism by which DNA separates into the two ends
of a dividing cell during telophase
c) The site of origin of DNA replication which speeds up
the rate of cell proliferation in eukaryotes
d) The repetitive nucleotide sequence at the ends of linear
chromosome, which protects the genes at the ends of the
chromosomes
The central dogma proposes that
a) DNA is translated into mRNA, which in turn is translated
into an amino acid sequence forming a peptide
b) mRNA is translated into DNA, which in turn is translated
into an amino acid sequence forming a peptide
c) DNA is transcribed into mRNA, which is in turn
translated into an amino acid sequence forming a peptide
d) none of the above
