Answer:

A. Auxotroph 4. requires at least one nutrient for growth

B. Conjugation  1. requires cell-to-cell contact

C. Hfr  6. E. coli strain with Ffactor integrated into bacterial genome  

D. Transduction 7. requires virus

E. F' 5. F factor that has picked up a piece of the bacterial genome

F. Transformation 3. uptake of DNA from external medium

G. Competent 2. capable of taking up DNA

Explanation:

Auxotrophs are those organisms able to synthesize organic compounds required for their growth.

Conjugation is the genetic transfer between bacteria through cell-to-cell contacts.

In bacteria, the Hfr chromosome is linearly transferred from F  to F- cells.

Transduction is a genetic process where exogenous DNA fragments are introduced into another cell via a viral vector.

The F factor (fertility factor) is a bacterial plasmid that allows to transfer genetic information between donor and recipient cells during conjugation.

Bacterial transformation is the horizontal transfer of genetic material by which bacteria obtain DNA from its environment.

In bacteria, competence refers to the ability to take up exogenous DNA from the external environment.
