Which process do phages use to deliver their genome into the host cytoplasm quizlet?

Which process do phages use to deliver their genome into the host cytoplasm?

During a lytic replication cycle, a phage attaches to a susceptible host bacterium, introduces its genome into the host cell cytoplasm, and utilizes the ribosomes of the host to manufacture its proteins.

How do bacteriophages enter into their host cell quizlet?

b)Penetration: The bacteriophage injects its DNA into the host cell.

How does bacteriophage DNA get into the host cell?

A bacteriophage attaches itself to a susceptible bacterium and infects the host cell. … Bacteriophages occasionally remove a portion of their host cells’ bacterial DNA during the infection process and then transfer this DNA into the genome of new host cells. This process is known as transduction.

What form does the phage DNA takes when it is injected into the host Mcq?

Entry: The phage injects its double-stranded DNA genome into the cytoplasm of the bacterium. DNA copying and protein synthesis: Phage DNA is copied, and phage genes are expressed to make proteins, such as capsid proteins.

What is the host for a phage?

Initially described a century ago by William Twort and Felix d’Herelle, bacteriophages are bacterial viruses found ubiquitously in nature, located wherever their host cells are present. Translated literally, bacteriophage (phage) means ‘bacteria eater’.

What is a phage receptor?

Phage receptors, which are bacteria-encoded cell-surface-exposed molecules, include proteins, lipopolysaccharides, teichoic acids, and capsules (Heller, 1992). … Even a modest alteration in a receptor’s structure can have dramatic effects on phage binding without overly affecting normal functioning.

What is a bacteriophage What is it made of quizlet?

Bacteriophages are composed of proteins that encapsulate a DNA or RNA genome, and may have relatively simple or elaborate structures. Their genomes may encode as few as four genes, and as many as hundreds of genes. Phages replicate within the bacterium following the injection of their genome into its cytoplasm.

What happens when a bacteriophage carrying bacterial DNA infects a new bacterium?

Transduction occurs when a bacteriophage containing bacterial DNA infects a recipient bacterium and transfers this bacterial DNA to the recipient bacterial host cell. This transferred bacterial DNA may then be incorporated into the genome of the recipient bacterium.

When a bacteriophage in its lytic phase carries?

When certain proviruses turn into virulent viruses thereby causing lysis of host cell, they may carry with them segments of host’s DNA.

How does a bacteriophage replicate in a bacterial cell?

Bacteriophages, also known as phages, are viruses that infect and replicate only in bacterial cells. … During a lytic replication cycle, a phage attaches to a susceptible host bacterium, introduces its genome into the host cell cytoplasm, and utilizes the ribosomes of the host to manufacture its proteins.
