A FRAME-SHIFT MUTATION INVOLVING THE ADDITION OF TWO BASE PAIRS IN THE LYSOZYME GENE OF PHAGE T4

Abstract
The primary structure of the lysozyme of the double-mutant strain eJ17eJ44 differs from that of the wild-type strain by a sequence of 5 amino-acids and the insertion of an additional amino-acid next to the altered 5. The mutation eJ17 results in the addition of 2 bases. The acridine dye proflavine causes the insertion of a base, the deletion of a base and the insertion of 2 bases. The lysozyme of the eJ17eJ44 strain was identical to that for the eJ42eJ44 strain except for the addition of an amino acid.
