Genetic recombination in _______ takes place in three ways: conjugation, transformation, and transduction. __________ is the transfer of genetic material between bacteria by direct cell-to-cell contact and involves DNA molecules called ______________. In contrast, ___________________ (does not require cell-to-cell contact) is the process where foreign DNA enters recipient__________ and recombines with the host\'s chromosome. __________________ is virus-mediated DNA recombination, in which ________________ can reproduce within infected host ________________. This type of recombination can be divided into two types, ___________________ ________________, which involves incorrect excision of the viral genome from the host chromosome and transfer of a few adjacent host genes. This type of transduction is limited to __________ _____________. The other type of viral recombination, ________________ ___________________, occurs when host genes are mistakenly packaged into the viral head. This type of recombination occurs only in _______________ ____________________.

Solution

Genetic recombination in BACTERIA takes place in three ways: conjugation, transformation, and transduction.

CONJUGATION is the transfer of genetic material between bacteria by direct cell-to-cell contact and involves DNA molecules called PLASMIDS.

In contrast, TRANSFORMATION (does not require cell-to-cell contact) is the process where foreign DNA enters recipient BACTERIA and recombines with the host\'s chromosome.

TRANSDUCTION is virus-mediated DNA recombination, in which BACTERIOPHAGE can reproduce within infected host BACTERIA.

This type of recombination can be divided into two types, GENERALIZED TRANSDUCTION which involves incorrect excision of the viral genome from the host chromosome and transfer of a few adjacent host genes.

This type of transduction is limited to LYTIC PHAGES.

The other type of viral recombination, SPECIALIZED TRANSDUCTION, occurs when host genes are mistakenly packaged into the viral head.

This type of recombination occurs only in LYSOGENIC PHAGE.
