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:

A normal human cell contains 46 chromosomes in total, 23 inherited from the father and 23 inherited from the mother. Each group of 23 chromosomes is called a set of chromosomes. A normal human cell, therefore, has two sets of chromosomes. In some organisms, entire chromosome sets have been duplicated. What term is given to a cell in an organism that has more than two sets of chromosomes?
