Bacteriophages consist of a Nucleic Acid molecule that is surrounded by a structure of proteins.
What else can I help you with?
What is the material that phages insert into bacteria?
Phages insert their genetic material, which is typically DNA, into bacteria. This genetic material carries the instructions for the phage to replicate itself within the bacterial cell.
What attaches to the bacteria and injects the hereditary material?
A bacteriophage. A virus that lands on the bacteria and injects the genetic material. Often, T even phages. ( T-2 and T-4 phages )
What virus infect bacteria?
Bacteriophages are viruses that infect and replicate within bacteria. These viruses inject their genetic material into a bacterium, which then uses the bacterium's machinery to produce more phages. This eventually leads to the lysis of the bacterium and release of new phages to infect other bacteria.
Why bacteriophage transfer only DNA or RNA into a bacteria but not the protein?
phages can range from 50nm to 200nm.This dimension dont favorizied virused to enty intairlly into their host bacteria.Cell wall of bacteria it is composed of peptidoglycan a glicoprotein that it protect bacteria again enviromental stress and agents.For this reason phages have evolved to inject their genome to the host bacteria.
What did hershey and chase discover after the p-labeled phages infected the bacteria most of the radioactive phosphorous found in the layer containing?
Hershey and Chase discovered that after the P-labeled phages infected the bacteria, most of the radioactive phosphorus was found in the viral DNA, while little to no radioactive sulfur (used to label protein) was found. This confirmed that genetic material, not protein, is responsible for heredity in viruses.
Can two phages infect bacteria at a time?
It can be.in this way we can obtain new phages thah share genes of bpth phages.
How did Hershey and Chase separate the phages from the bacteria?
Blender

What viruses infaect bacteria?
Bacteriophages. The T even series is the most commonly presented. T-4 'phages, for instance.
Hershey and chase removed the phages from the surface of the bacteria by using?
They tore of the surface of the surfaces of the bacteria with the help of a blender.

How are the lytic cycle and lysogenic cycl diffrent?
Phages have lytic or lysogenic cycle to reproduce themself.Phages that have lytic life cycle it kill bacteria after new progenicy of phages are relaset from host bacteria.Phages with lysogenic cyclel it integrate their DNA to the host bacteria.However, when bacteria that carry genetic material of lysogenic phages are posed to stress can switch to the lytitic cycle to produce a new progeny of pahages.
What is meant by germs even get germed?
Bacteria can be attacked by viruses called bacteriophages or somtimes just 'phages.
What are three ways bacteria may win the battle against the phages?
-natural selection -restriction enzymes -lysogeny
