genetics questions. Please help thank you!

Answer 1

1-3)

a) The type of gene transfer between Hfr cell and f- is through Conjugation.

b) Bacteriophage are transferring genetic material through transduction from one bacterium to another

c) Gene transfer by uptake of naked DNA is through Transformation

d) Genes are transferred between bacteria in plaques by Transduction, Transformation or conjugation.

e) Direct contact between bacterial cells transfers the genetic material is through Conjugation.

f) Transfer of plasmid DNA is through Conjugation.
