Radioactively tagged bacteriophages are used to confirm that DNA, not protein, is injected into host cells during infection. The radioactively labeled DNA can be detected inside the host cells after infection, providing evidence that DNA is the genetic material transferred by the bacteriophages. This experiment was crucial in establishing DNA as the genetic material in organisms.
Hershey and Chase used radioactive Sulfur to label viral proteins, as proteins contain sulfur. By growing the viruses in a culture containing both radioactive Sulfur and Phosphorus, they could differentiate between viral proteins (labeled with Sulfur) and viral DNA (labeled with Phosphorus). If they had only used one radioactive substance, they would not have been able to determine the specific molecule (protein or DNA) that the virus injected into the host cell.
Hershey and Chase attached radioactive sulfur to proteins in the bacteriophage's outer coat in one experiment, and to DNA in another experiment, to determine which molecule was injected into the host bacteria during viral infection. They found that only DNA, not proteins, was passed on to the host bacterium. This confirmed that DNA is the genetic material responsible for heredity.
The coating of a virus is made of protein molecules. These proteins can vary in composition and structure, helping the virus to attach to host cells and invade them.
Viruses are injected into host cells primarily through a process called viral entry, which can occur via various mechanisms. For many viruses, this involves binding to specific receptors on the host cell's surface, followed by fusion of the viral envelope with the cell membrane or endocytosis. Once inside, the viral genetic material is released into the host cell, allowing it to hijack the cell's machinery to replicate and produce new viral particles. This process can vary significantly among different types of viruses.

In myoblast transfer, millions of immature muscle cells are injected into an affected muscle. The goal of the treatment is to promote the growth of the injected cells, replacing the defective host cells with healthy new ones

No, a virus is not a chemical. Viruses are biological entities that rely on host cells to reproduce and do not meet the definition of a chemical substance.

The virus attaches to the host cells membrane.
It occurs when the DNA from the virus is injected into the host cell.
The substance a phage leaves outside its host cell is typically referred to as the "phage progeny" or "phage particles." These particles can include newly synthesized phage DNA and proteins, as well as the phage capsid that encapsulates the genetic material. This material can go on to infect other host cells and continue the phage replication cycle.
