What describes the lytic and lysogenic cycles?
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.
Which best describes the lysogenic cycles?
Which best describes the lysogenic cycle? In bacteria, the direct transfer of DNA between two cells that are temporarily joined.
What is the lytic and lysogenic cycles quizlet?
Lytic Cycle. a viral reproductive cycle in which copies of a virus are made within a host cell, which then bursts open, releasing new viruses. Lytic cycle diagram. Lysogenic Cycle. a viral reproductive cycle in which the viral DNA is added to the host cell's DNA and is copied along with the host cell's DNA.
What are two main differences between the lytic and lysogenic cycles?
Lytic vs Lysogenic Cycle
| Lytic Cycle | Lysogenic Cycle |
|---|---|
| Genetic recombination in the host bacterium not allowed | Genetic recombination in the host bacterium allowed |
| The cellular mechanism of the host cell is totally undertaken by the viral genome | The cellular mechanism of the host cell is somewhat disturbed by the viral genome |
What happens in lysogenic cycle?
The lysogenic cycle: The phage infects a bacterium and inserts its DNA into the bacterial chromosome, allowing the phage DNA (now called a prophage) to be copied and passed on along with the cell's own DNA.
What happens during lysogenic cycle?
In the lysogenic cycle, phage DNA is incorporated into the host genome, forming a prophage, which is passed on to subsequent generations of cells. Environmental stressors such as starvation or exposure to toxic chemicals may cause the prophage to be excised and enter the lytic cycle.
What happens during the lysogenic cycle?
In the lysogenic cycle, phage DNA is incorporated into the host genome, forming a prophage, which is passed on to subsequent generations of cells. Environmental stressors such as starvation or exposure to toxic chemicals may cause the prophage to be excised and enter the lytic cycle.
Is lytic or lysogenic faster?
The lytic cycle is a faster process for viral replication than the lysogenic cycle.
What is the lytic cycle of a virus?
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.
What is the lysogenic cycle simple definition?
The lysogenic cycle is a method by which a virus can replicate its DNA using a host cell. Typically, viruses can undergo two types of DNA replication: the lysogenic cycle or the lytic cycle. In the lysogenic cycle, the DNA is only replicated, not translated into proteins.
What happens in the lysogenic cycle?
The lysogenic cycle: The phage infects a bacterium and inserts its DNA into the bacterial chromosome, allowing the phage DNA (now called a prophage) to be copied and passed on along with the cell's own DNA.
What is lysogenic life cycle?
The lysogenic cycle is a method by which a virus can replicate its DNA using a host cell. Typically, viruses can undergo two types of DNA replication: the lysogenic cycle or the lytic cycle. In the lysogenic cycle, the DNA is only replicated, not translated into proteins.
What does the lysogenic cycle do?
The lysogenic cycle is a method by which a virus can replicate its DNA using a host cell. Typically, viruses can undergo two types of DNA replication: the lysogenic cycle or the lytic cycle. In the lysogenic cycle, the DNA is only replicated, not translated into proteins.
What is lytic cycle of virus?
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.
What happens in a lysogenic cycle?
The lysogenic cycle: The phage infects a bacterium and inserts its DNA into the bacterial chromosome, allowing the phage DNA (now called a prophage) to be copied and passed on along with the cell's own DNA.
How does the lytic cycle work?
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.
