Lesson: Genetic and Chromosomal Mutations Biology

In this lesson, we will learn how to define what a mutation is, recognize various types of mutations, and state some potential impacts of mutations.

Lesson Plan

Students will be able to

define mutation as a change in the DNA base sequence,
state the potential effects of mutations on proteins produced as being beneficial, neutral, or harmful,
recognize substitution, insertion, and deletion gene mutations,
recognize duplication, inversion, and deletion chromosomal mutations,
distinguish between spontaneous mutations and induced mutations.

Q1:

True or False: If a mutation occurs in a normal body (somatic) cell of an organism, that mutation will be passed on to that organism’s offspring.

Q2:

Which of the following correctly differentiates between spontaneous and induced mutations?

Q3:

In a normal human cell, there are two copies of each chromosome. Chromosomal mutations can duplicate entire chromosomes. What term is given to a human cell that has more than two copies of a chromosome?
