What are the two parts of a bacteriophage?

The tailed phages have three major components: a capsid where the genome is packed, a tail that serves as a pipe during infection to secure transfer of genome into host cell and a special adhesive system (adsorption apparatus) at the very end of the tail that will recognise the host cell and penetrate its wall.

What are the two reproductive mechanisms of phage?

1: 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.

What elements make up bacteriophage?

Like all viruses, phages are simple organisms that consist of a core of genetic material (nucleic acid) surrounded by a protein capsid. The nucleic acid may be either DNA or RNA and may be double-stranded or single-stranded.

What are the 2 types of phage life cycle and how do they relate to each other?

Some phages can only reproduce via a lytic lifecycle, in which they burst and kill their host cells. Other phages can alternate between a lytic lifecycle and a lysogenic lifecycle, in which they don't kill the host cell (and are instead copied along with the host DNA each time the cell divides).

What are the functions of the parts of a bacteriophage?

Bacteriophage enzymes destroy the bacterial cell wall from both outside and inside by hydrolyzing carbohydrate and protein components. All these proteins protect phage genetic material, secure injection of the phage nucleic acid into the bacterial cell, and promote phage propagation.

What are the two simple components that make up a virus?

The simplest virions consist of two basic components: nucleic acid (single- or double-stranded RNA or DNA) and a protein coat, the capsid, which functions as a shell to protect the viral genome from nucleases and which during infection attaches the virion to specific receptors exposed on the prospective host cell.

What structures are components of both viruses and cells?

According to the information in the Venn diagram, the only structure or component that a virus and a cell have in common is nucleic acid. The virus lacks all the other cellular structures, and without them, it cannot exist, thrive, and reproduce on its own.

What are lytic phages?

Lytic phages take over the machinery of the cell to make phage components. They then destroy, or lyse, the cell, releasing new phage particles. Lysogenic phages incorporate their nucleic acid into the chromosome of the host cell and replicate with it as a unit without destroying the cell.

Which part of a phage is involved in adsorption?

Peptidoglycan, or murein, is an important component of the bacterial cell wall and is often involved in bacteriophage adsorption.

Which of the following is a characteristic of a bacteriophage?

A bacteriophage is a virus that infects and replicates within a bacteria and archaea. Bacteriophages reproduce by two methods, namely, the lytic cycle and the lysogenic cycle. They are made up of proteins that surround a DNA or RNA genome.

Which enzyme is present in bacteriophage?

Bacteriophage lytic enzymes, or lysins, are highly evolved molecules produced by bacterial viruses (bacteriophage) to digest the bacterial cell wall for bacteriophage progeny release.

What two stages of replication do both cycles have in common?

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.

Which of the following are the two types of structure typical of most viral capsids?

Virus capsids predominantly come in two shapes: helical and icosahedral. The helix (plural: helices) is a spiral shape that curves cylindrically around an axis. It is also a common biological structure: many proteins have sections that have a helical shape, and DNA is a double-helix of nucleotides.

Which component of a virus is injected into a cell?

Viral penetration: The viral capsid or genome is injected into the host cell's cytoplasm.
