Which of the following features are common to transformation, transduction, and conjugation? (1) unidirectional transfer of genes (2) incomplete gene transfer (3) homologous recombination (4) meiosis occurring in the recipient

Answer: 1,2 and 3.

The following are common to transformation, transduction and conjugation.

1. Unidirectional transfer of genes.

2. Incomplete gene transfer.

3. Homologous recombination.

Explanation:

Transformation is the taking up of free DNA from the environment.

Transduction is the transfer of DNA by bacteria to a viruses.

Conjugation is the transfer of Plasmid or circular DNA through a tube between the cells. Incomplete DNA are transferred unidirectional.
