Which is the correct description of the 2nd step in the Lytic cycle?

Attachment and entry. The virus physically attaches to the host and enters the cell membrane.

Explanation:

Lytic versus lysogenic cycle: A temperate bacteriophage has both lytic and lysogenic cycles. In the lytic cycle, the phage replicates and lyses the host cell. In the lysogenic cycle, phage DNA is incorporated into the host genome, where it is passed on to subsequent generations.

Prokaryotic cells typically have a single, circular chromosome located in the nucleoid.
