Question
Please answer only 6-9 PLEASE! Which of the following may account for the process of gene conversion? A) DNA mismatch repair B) DNA gap repair C) Photolyase activity D) Nucleotide excision repair E) More than one of the above In a cloning experiment, you use a vector that contains a gene as selectable marker. If the competent cells are grown on X-Gal and IPTG, which colonies would contain chromosomal DNA? A) The white colonies B) The blue colonies C) Half the total colonies D) None of the colonies E) None of the answers are correct
Explanation / Answer
6. C. Southern blotting. Explanation: In the Southern blotting technique oligonucleotides are designed that are similar to the target sequence. The oligo's are chemically synthesized and are useful for screening a DNA library.
7. A competent cell would be able to D) Take up DNA from the external environment.
8. A) DNA mismatch repair. Gene conversion is the process in which one allele in a heterozygote is converted to the other by a process of a mismatch repair.
9. If the competent cells are grown on X-Gal and IPTG, the A) white colonies would contain chromosomal DNA.
