the spacecraft shaped virus attaches to the host cells and as it leaves it kills the host cell

the spacecraft virus attaches to the host cell injects DNA as the virus leaves it kills the host cell

Detailed explanation-1: -In the lytic cycle, the virus attaches to the host cell and injects its DNA. Using the host’s cellular metabolism, the viral DNA begins to replicate and form proteins. Then fully formed viruses assemble. These viruses break, or lyse, the cell and spread to other cells to continue the cycle.
Detailed explanation-2: -In a lytic cycle, the virus introduces its genome into a host cell and initiates replication by hijacking the host’s cellular machinery to make new copies of the virus. Once infection is complete, the newly replicated and assembled virus particles are released through lysis of the host cell into the surrounding waters.
Detailed explanation-3: -Lytic cycle Immediately following injection into the host cell, the phage genome synthesizes early proteins that break down the host DNA, allowing the phage to take control of the cellular machinery.
Detailed explanation-4: -The lytic cycle involves the reproduction of viruses using a host cell to manufacture more viruses; the viruses then burst out of the cell. The lysogenic cycle involves the incorporation of the viral genome into the host cell genome, infecting it from within.
Detailed explanation-5: -What happens to the host bacteria’s DNA after the bacteriophage injects its DNA/RNA into the cell? It puts the viruses DNA into the cells own DNA. The bacteria pass this “combined” DNA on to the daughter cells. The bacteria continue to reproduce and finally enter the lytic cycle when this happens.
