You study the gene incorporation in recipient using HFR and get the following sequences-P-W-A-K, W-L-I-K, A-K-I-L, W-P-R-T-W-L. What is the order of the gene?
For complete HFR to enter the recipient, how much time should the two bacterial cells be in contact?
In an experiment of determining the order of gene in bacteria we use HFR which is gal+, Lac+, Ara+ and His+. If the recipient is negative for all these genes, and we selectively choose Gal + and get the pattern-100 % recipients are Gal +30% are His+55% are Lac +And only 5% are Ara+What would be our inference?
If genes enter the different F- cells from different HFRs in the order as shown- What is the order of the gene where columns are for different HFR and values denote time?
In and interrupted mating experiment, it is seem that the after 10 mins AziR gene in recipient, after 20 minuites there is appearance of tonR and after 15 mins the recipient is lac+ , but the recipient is almost never his+. Where in the genome is the ori of transfer?

All the genes in the HFR that is transferred to the recipient cell before breakage of the conjugation channel is incorporated in the recipient genome. State whether it is true or false.
A HFR bacteria mates with an F- plasmid containing bacteria. What will be the type of bacteria after conjugation is complete?
