Mutation is a random and non-adaptive process.This was first proven by:
A) Lysenko and Lamarck, using the removal of mouse tails as an environmental stress.
B) Joshua and Esther Lederberg, using the removal of mouse tails as an environmental stress.
C) Lysenko and Lamarck, using replica plated E. coli and streptomycin as an environmental stress.
D) Joshua and Esther Lederberg, using replica-plated E. coli and streptomycin as an environmental stress
E) Mutation is not a random, nonadaptive process.

Question

Quizplus · Accepted Answer

Joshua and Esther Lederberg conducted experiments using replica-plated E. coli and streptomycin, which demonstrated that mutations are a random and non-adaptive process, as the mutations occurred regardless of whether they were beneficial, harmful, or neutral to the organism. The experiments also showed that mutations were not induced by the environmental stress of exposure to streptomycin. This refuted the idea proposed by Lysenko and Lamarck that environmental stress could trigger directed mutagenesis.
