Use the drop-down menus to answer the questions about genetic recombination. involves the transfer of genetic material from one
Tresset [83]

The right matches are:

• Involves the transfer of genetic material from one bacteria to another ==> Genetic recombination (all 3).

• Involves scraps of genetic material ==> Transformation.

• Uses a virus to transmit genetic material ==> Transduction.

• Uses a pilus to transmit genetic information ==> Conjugation.

• Introduces new genetic material to a bacterium ==> Genetic recombination (all 3).

In molecular biology the term genetic recombination is often used as a synonym for DNA recombination, that is, the processes by which one DNA (or RNA) molecule is cut off, then joined to another.

There are three possible mechanisms in the bacterium: bacterial conjugation, bacterial transformation and transduction.
