Question

Bacteriophages have very high copy numbers of their genome within the bacterial cells because

1)Their replication is linked to replication of chromosomal DNA

2) Their number per cell is high

3) Of absence of their own ori'sequence

4)Of lack of vital genes​

Answer 1

Explanation:

1 is the correct answer

Answer 2

Answer:

1)Their replication is linked to replication of chromosomal DNA

Explanation:

• Bacteriophage (phage) viruses are viruses that infect bacteria alone.
• Phage can be found in a wide range of sizes and shapes. They are divided into two groups based on their morphology and genome type.
• A phage particle is made up of a single nucleic acid (DNA or RNA) and a protein capsid that shields the genetic material.
• The great majority of phage also have a tail (composed of proteins) that allows them to recognise a receptor on the host bacterium's surface.
• Phages are now acknowledged as the most abundant living entities on our planet, and they play critical functions in maintaining the microbial ecosystem's ecological equilibrium.
