Compare and contrast how the lagging strand is replicated in E. coli and in eukaryotes. Highlight the steps that are the same or similar, as well as the aspects of lagging strand synthesis that differ.
A mutant DNA strand was transcribed then translated to proteins.
a. What is the protein product of the mutant DNA strand?
The sequence of the mutant strand is shown below:
5'-TGCCATAACTGTTCGTACTGGCAAATTGCC-3'
3'-ACGGTATTGACAAGCATGACCGTTTAACGG-5'
b. The mutation altered the sequence of the wild type template DNA such
that a degenerate codon for a basic amino acid in the wild type was
converted to a non-degenerate codon resulting in the sequence for the
mutant strand shown. What was the original amino acid?
c. Compare the charges and pl of the mutant peptide and the normal (wild-
type) peptide at physiological pH?
Strand directed mismatch repair corrects copying erros based on
which ones apply to sentence above?
a. the strand containg breaks in the sugar backbone of the replicated DNA
b. structurral instabilities created between oncorrect base pairing and associated histone proteins
c. mutations that are evolutionary beneficial to an organims and recults in these areas of the genetic code to be turned off
d. methylation of adenosine in GATC sequences during bacterial DNA replication
e. repair sequence motifs that attract DNA polymerase gamma
