Question

In Figure , which gene on the bacterial chromosome will be transferred last in strain Hfr5?

(a)
Hfr1
1 Transfer always
begins within F,
and the orientation
2 In Hfr1, F is integrated
between the leu gene
and the azi gene;....
of F determines the
thr
direction of transfer.
thi
leu
F factor
his
azi
Chromosome
gal
pro
3.so the genes
are transferred
beginning with leu.
lac
leu thr thi his gal lac pro azi

(b)
Hfr5
4 In Hfr5, F is integrated
between thi and his.
thr
thi
leu
F factor
his
azi
Chromosome
5 F has the opposite
orientation in this
pro
chromosome; so the
genes are transferred
beginning with thi.
gal
lac
thi thr leu azi pro lac gal his
Genetic map
The orientation of the F factor in an Hfr strain determines the
dırection of gene transfer.
Arrowheads indicate the origin and direction of transfer.
