Describe the contributions of hershey and chase to the understanding that DNA is the genetic material?
Hershey and Chase radioactively labelled T2 bacteriophage with P (DNA) and S (protein) to determine if protein or DNA carried the genetic material. They let the bacteriophage infect E.coli. The radioactive material found in the host E.coli contained the radioactive P (found in DNA) as the bacteriophage had multiplied inside the cell, but the radioactive S was not found inside the cell. Therefore DNA is the hereditary molecule resorce - some other guy off the internet
What did Hershey and Chase show the genetic material of the t2 bacteriophage was?
DNA is the genetic material. However, Hershey-Chase also stated that some little sulfur containing material also entered the bacterial cell. Looking at these two conclusions, Hershey-Chase could not reach a definite conclusion as to whether DNA or Protein contains the genetic material. The conclusion came from Watson-Crick who stated that the sulfur containing material could have entered the cell due to the fact that DNA replication and subsequently translation of the mRNA leads to the synthesis of sulfur containing protein which were found in the bacterial cell.
A bacteriophage typically attaches to the bacterium and then?
It's genetic material and some enzymes sometimes which hijack the bacteria into making more viruses.
What is the name for a DNA virus specifically suited for the infestation of bacteria?
Bacteriophage.
Which best describes transduction in bacteria?
Bacteria transfer DNA with a bacteriophage.
Hershey and chase concluded that the genetic material of the bacteriophage was?
dna(:
What result did Hershey and chase observe?
they concluded that the genetic material of the bacteriophage was DNA, not protein

Why was Alfred Hershey and Martha Chase's experiment so important?
In their experiments, Hershey and Chase showed that when bacteriophages, which are composed of DNA and protein, infect bacteria, their DNA enters the host bacterial cell, but most of their protein does not. Although the results were not conclusive, and Hershey and Chase were cautious in their interpretation, previous, contemporaneous and subsequent discoveries all served to prove that DNA is the hereditary material.
Is T4 bacteriophage a DNA or RNA virus?
DNA
What does bacteriophage inject into a cell?
A bacteriophage ("eater of bacteria") inject their DNA (or RNA) into the cell.
What are difference between macrophage and bacteriophage?
bacteriophage is a virus that kills bacteria
What is the insert capacity of a lambda bacteriophage vector in DNA cloning?
We can insert about 5-25 kb sized foreign DNA in a lambda bacteriophage vector.
Is a T4 bacteriophage virus living or non living?
Bacteriophage viruses are nonliving. They are DNA or RNA encapsulated in a protein coated capsule with recognition sites to bind to specific target sites on bacteria and insert their genetic material for viral replication or to induce changes in the bacterial genetic material.

Which part of bacteriophage contain the DNA?
Head region
Which viruses inject their DNA?
Bacteriophage T4 virus
