Question

This activity requires that you sort statements according to whether they are associated with transformation, conjugation, transduction or all. Drag the statement to the gene transfer mechanism with which it is associated. A statement may be associated with more than one mechanism.

*This mechanism was first explored by Griffith as he studied smooth and rough strains of Streptococcus pneumonia

*Extracellular DNAses would block this transfer mechanism.

*This mechanism is initiated by cells with F plasmids.

*This mechanism may result in the transfer of genes that encode antibiotic resistance

*This mechanism requires cell-to-cell contact.

*A chemical that blocked the formation of a pilus would block this genetic transfer mechanism.

*This mechanism of genetic transfer always involves a one-way transfer from a donor cell to a recipient cell.

*A virus that infects bacteria is a key component in this transfer mechanism.

transformation conjugation, transduction all mechanisms

Explanation / Answer

Answer:

Transformation:

1. This mechanism was first explored by Griffith as he studied smooth and rough strains of Streptococcus pneumonia.

2. Extracellular DNAses would block this transfer mechanism.

Conjugation:

1. This mechanism is initiated by cells with F plasmids.

2. This mechanism requires cell-to-cell contact.

3. A chemical that blocked the formation of a pilus would block this genetic transfer mechanism.

Transduction:

1. A virus that infects bacteria is a key component in this transfer mechanism.

All mechanisms:

1. This mechanism may result in the transfer of genes that encode antibiotic resistance.

2. This mechanism of genetic transfer always involves a one-way transfer from a donor cell to a recipient cell.
