During the late 1950s and early 1960s, Werner Arber and several others extended the work of an earlier Nobel laureate, Salvador Luria, who observed that bacteriophages (viruses that infect bacteria) not only induce hereditary mutations in their bacterial hosts but at the same time undergo hereditary mutations themselves. Werner Arber’s research was concentrated on the action of protective enzymes present in the bacteria, which modify the DNA of the infecting virus e.g., the restriction enzyme, so-called for its ability to restrict the growth of the bacteriophage by cutting the molecule of its DNA to pieces.
The Roaring Twenties
The Roaring Twenties was a time when young women fought against the traditional gender norms. These women (commonly referred to as flappers) would wear short dresses, smoke in public, drink alcohol, and dance in jazz clubs. These acts were all frowned upon for women to do at the time. While in the twenties these women were often viewed as immoral and dangerous, we have since come to recognize them as pioneers of women’s independence, as they pushed back against gender norms.

Though castes don´t exist formally in Indian law, they exist in reality and social and racial divisions run still deep in India.
