Question

Under the right circumstances, the lysogenic cycle changes to the lytic cycle. Explain whether the lytic cycle can change to the lysogenic cycle. Explain your answer in 3–5 sentences.(4 points)

Answer 1

Answer:

If the conditions where the viral DNA is inserted are not adequate, the lytic cycle can change to the lysogenic cycle.

Explanation:

The lytic cycle occurs when a virus inserts its viral nucleic acid into a bacterial cell. At that moment, the viral nucleic acid causes all the functions of the bacterial cell to be interrupted and work in favor of that viral nucleic acid, forming proteins for it and allowing the creation of new viruses. When the new viruses are formed, the cell breaks down and the new viruses are released to infect other bacterial cells. The lysogenic cycle, in turn, occurs when the virus inserts its viral nucleic acid into the bacterial cell, but does not interfere with the functions of that cell, however it adapts and begins to be part of the bacterial DNA. In this cycle the cell does not rupture, but it spreads the viral nucleic acid through the cell cycle, where each daughter cell is already produced with the viral molecule.

The lysogenic cycle can change to the lytic cycle after a while, this is even common. However, although more difficult to happen, there are also times when the lytic cycle can change to the lysogenic cycle. This only happens when the lysogenic cycle has already changed to the lytic cycle, but the conditions are no longer appropriate, making the viral material return to the lysogenic cycle.
