Consider the following statements regarding DNA replication and choose the correct answer:
1. The very first requirement of DNA synthesis is the presence of a template or plan along which the new strand is to be constructed
2. The second requirement is of a DNA-dependent-DNA polymerase or simply DNA polymerase enzyme
3. A DNA Pol cannot join two free nucleotides; one of them must be anchored by hydrogen bonds to a DNA strand
4. Replication takes place bidirectionally

The gene to be disrupted is cloned and a selectable marker is inserted. What should be the effect of selectable marker?
Stable acquisition of the marker can take place only if a double crossover over the flanking sequence and their chromosomal counterparts causes the marker’s integration into the chromosome.
You are checking the sequence of 3 genes using generalized transduction mapping. The recipient is Leu-, AziS, Thr- while the donor is Leu+, AziR, Thr +. If you select the Leu+ as marker, AziR would be 50% while Thr+ would be 2%. If you select Thr+ as marker Leu+ would be 3% and AziR would be 0%. What is the sequence?
