What is T2 phage?
Q: What is T2 phage?
A: T2 phage, also known as Enterobacteria phage T2, is a virus that infects Escherichia coli bacteria.
Q: What type of DNA does T2 phage contain?
A: T2 phage contains linear double-stranded DNA.
Q: Is T2 phage covered by a protective protein coat?
A: Yes, T2 phage is covered by a protective protein coat.
Q: What group of viruses does T2 phage belong to?
A: T2 phage belongs to a group of viruses known as the 'T4-like viruses'.
Q: How does T2 phage infect E. coli cells?
A: The DNA of T2 phage is injected into E. coli cells, which quickly turn the E. coli cell into a T2-producing factory. New phages are released when the cell ruptures.
Q: What did the Hershey-Chase experiments show?
A: The Hershey-Chase experiments showed that the DNA of viruses is injected into the bacterial cells, while most of the viral proteins stay outside. The injected DNA molecules cause the bacterial cells to produce more viral DNA and proteins. These discoveries showed that DNA, rather than proteins, is the hereditary material.
Q: Who conducted the Hershey-Chase experiments?
A: The Hershey-Chase experiments were done by Alfred Hershey and Martha Chase.
