Mechanisms of Mutation
Learning Objectives
• Describe the mechanisms of mutations
• Study the Hugo de Vries mutation theory
Hugo de Vries
• Knew about Mendel’s work
• Professor of Botany in Amsterdam
• Strong proponent of ______________________________________
• Theory of __________________
• Species evolved from other species due to sudden large
changes in traits
• Studied Oenothera lamarckiana
• Variations due to chromosomal mutations not gene mutations.

Types of Mutations
• Chromosomal (from last term)
• Gene
• Point (______________________)
• Silent: No effect on protein (amino acid sequence)
• Missense: Change to the amino acid produced in
translation
• ________________: Premature STOP to translation.
• Frameshift
• Insertion: addition of a base
• Deletion: _______________ of one base
• Duplication: repeat of DNA sequence
