Answer:
The correct answer is A bacteriophages inject only DNA into the bacteria.
Explanation:
Bacteriophages are a specific type of virus that infect bacteria.During the course of infection bacteriophage releases an enzyme known as lysozyme which creates a hole in the cell wall of the bacteria.
After doing that(creating a hole) bacteriophage inject its DNA inside the bacterium.
The injected DNA undergo gene expression by utilizing the gene expression machinery of bacteria which ultimately result in the formation of coat protein.The DNA is then packed within the coat protein to form progeny phages.The progeny phages then disrupt the cell wall and get released from the bacterium in search of a new host.
Benefits of living on land: Sunlight is brighter, since it doesn't have to go through water first. More carbon dioxide in the atmosphere than in the ocean. Mineral nutrients are plentiful in the soil.
