The importance of phage in fundamental biology,ned from phage studies applicable to other organisms? In the second subsection we will consider the facile exchanges of genetic material between bacteriophages and bacterial cells that lead us to suppose that they operate on the same genetic basis.

In such cases phage is

It is clearly efficient, otherwise phages would long ago have become extinct, yet it is common knowledge that phage preparations in the laboratory gradually lose their infectivity and eventually become useless.

The importance of phage in fundamental biology,meated the science of biology in the past two decades. The chapter falls naturally into three subsections. First and foremost is the concept of the physical nature of the gene that has been provided by studies using phage. It is not true that Hershey and Chase’s experiments first showed that genes w

For anyone who has not yet read biology or biochemistry up to degree standard, Stent’s ‘Molecular Genetics’ is strongly recommended, and Mathews’ ‘Bacteriophage Biochemistry’ for the more erudite.
