When an integrated prophase excises taking part of the host

When an integrated prophase excises, taking part of the host genome with it, it can transfer that DNA to a recipient by a process known as: conjugation. transformation. transduction. transfection. None of the above. Which of the following statements CORRECTLY describes the nutritional medium prepared for bacterial growth? Selective medium contains all the required nutrients allow all bacterial strains to grow. Minimal medium contains very few required ingredient that allow only phototrophic bacteria to grow. Autotrophic strains are capable of growing on minimal medium as they can synthesize what they need. Complete medium contains all the substances required for prototroph but not for auxotroph for growth and reproduction. The prepared fresh sterile medium can support the growth of bacteria present indefinitely.

Solution

18 . C) Tranduction
Transduction is the process in which a transducing phage inserts the donor DNA into the recipients chromosome and the donor DNA is included in the recipients chromosome due to recombination.

19. D) complete medium that contains all necessary substances required for phototrophs but not auxotrophs.
The Nutrient agar , the most commonly used medium for growth of bacteria that contains all the necessary ingredients, carbon source, proteins, yeast extract , NaCl, that would support growth of all bacteria except auxotrophic.
