Question 5
There is no template used during repair
Question 6
Statements 2,4,5 are true
Question 5 1 pts Non-homologous end joining is "error prone" because There is no template used...
In non-error prone DNA repair which of the following is usually the initial step in repairing a damage base: A. Excision of a small region around the damaged base. B. The binding of a sensor protein to the damaged region of DNA. C. The re-synthesis of the removed segment of DNA by DNA polymerase. D. The integrity of the resynthesized sugar-phosphate backbone is restored by ligase. E. None of the answers listed above (ABCD) are correct.
Question 3 1 pts Errors originating from DNA polymerase slippage are associated with Lynch syndrome Fragile X Xeroderma pigmentosum Cockayne syndrome Huntingtons disease Question 4 1 pts Base excision repair and nucleotide excision repair are similar in that Both use the undamaged strand as template Both are "error free" repair mechanisms The final steps of the repair process are shared Both resolve double-stranded DNA breaks
Question 5 1 pts The condition, xeroderma pigmentosum, is caused by dimerization of thymine bases when UV damage to DNA is not repaired. What mechanism exists to repair this kind of damage to DNA? proofreading nucleotide mismatch repair nucleotide excision repair phosphodiester substitution Question 6 1 pts Information obtained by Franklin from X-ray crystallography on DNA suggested that it is a
QUESTION 1: You are inserting a gene into an MCS found within the LacZ gene. Using blue/white colony selection, why could you assume that white colonies have modified plasmids? a. A blue colony means the LacZ reading-frame was disrupted b. A blue colony means your gene has mutations c. A white colony means the LacZ reading-frame is intact d. A white colony means the LacZ reading-frame was disrupted QUESTION 2: You are performing a PCR using primers with a sequence perfectly...
