Hershey and Chase examined the infected cells and found that they contained _____

Here is the answer to After allowing phages grown with bacteria in a medium that contained 32P and 35S, Hershey and Chase used a centrifuge to separate the phage ghosts from the infected cell. They then examined the infected cells and found that they contained _____, which demonstrated that _____ is the phage’s genetic material.

Phage

Phages are viruses that invade bacteria and the genetic material that confers biological traits to the host bacterium. Phages must be parasitic within living bacteria and have strict host specificity, which depends on the molecular structure and complementarity of phage adsorption organs and surface receptors of recipient bacteria.

Phages are the most prevalent and widely distributed group of viruses. Phages can usually be found in places full of bacterial communities, e.g., soil, intestines of animals.

Phages are a general term for viruses that infect microorganisms such as bacteria, fungi, algae, actinomycetes, or spirochetes, and are called phages because some of them can cause lysis of the host bacteria.

They were first discovered in Staphylococcus and Shigella at the beginning of this century. As a type of virus, phages have some characteristics of viruses: they are tiny; they do not have a complete cell structure, and they contain only a single nucleic acid. It can be considered a “predator” of bacteria.

The phage genome contains many genes, but all known phages use the bacterial ribosome, various factors required for protein synthesis, various amino acids, and energy production systems to grow and proliferate in the bacterial cell. Once away from the host cell, phages can neither grow nor replicate.

Phages are a type of virus that is unique in that it uses bacteria as its host, the better-known phage being the T2 phage that uses E. coli as its host. Like other viruses, phages are just a mass of genetic material wrapped in a protein shell, and most phages also have a “tail” that is used to inject genetic material into the host.

Phages are a common organism and are often accompanied by bacteria. They can be found in places where bacterial communities are abundant, such as soil and animal guts. The most abundant phage in the world is seawater.

Phages are small in size and can be tadpole-shaped, microspherical, and rod-shaped, with the tadpole shape being the most common. Phages are composed of nucleic acids and proteins. Protein plays the role of protecting nucleic acid and determines the shape and surface characteristics of phage. Its nucleic acid is of only one type, DNA or RNA, double- or single-stranded, and looped or thread-like.

Correct Answer

Here is the correct answer to After allowing phages grown with bacteria in a medium that contained 32P and 35S, Hershey and Chase used a centrifuge to separate the phage ghosts from the infected cell. They then examined the infected cells and found that they contained _____, which demonstrated that _____ is the phage’s genetic material.

After allowing phages grown with bacteria in a medium that contained 32P and 35S, Hershey and Chase used a centrifuge to separate the phage ghosts from the infected cell. They then examined the infected cells and found that they contained DNA, which demonstrated that DNA is the phage’s genetic material.
