Question

Which of the following statements is TRUE concerning the work of the Esther and Joshua Lederberg?
A)Their work demonstrated that mutations in organisms arise in response to environmental conditions.
B)Their work demonstrated that mutations are determined by an organism's "needs."
C)Their work demonstrated that mutations cannot occur randomly in organisms.
D)Their work relied on a technique of bacterial culture known as "replica plating."
E)Their work relied on a technique of bacterial culture known as "replica plating," and demonstrated that mutations occur randomly in organisms.

Accepted Answer

Esther and Joshua Lederberg's work is notable for the development of the replica plating technique, which was crucial in demonstrating that mutations in bacteria occur randomly, not in response to environmental conditions. This technique allowed for the easy identification of bacterial mutants and was instrumental in advancing the understanding of genetic variation and natural selection.
