Types of DNA Mutations and their Effects on the Protein

What are the various types of genetic mutations in terms of how they occur, as well as their effects on the DNA sequence and the resulting protein product?

What are some examples of each of the main types of genetic mutations and how can they be identified?

Solution Preview

Mutations are permanent changes made in the DNA sequence.

Mutations can be categorized in various ways:

1. According to how the mutation occurred:

a. Spontaneous mutations occur as a result of an error made during DNA replication.

b. Induced mutations are caused by agents outside the cell such as chemicals and radiation.

2. According to the effect the mutation has on the DNA sequence.

a. Point Mutations - mutations that occur at a specific base position in the ...

Solution Summary

This solution consists of an explanation of the categorization of genetic mutations, based on how they occur and their effect on the DNA sequence and resulting protein product. A worksheet is also provided to help the student practice identifying the types of mutations, as well as to practice converting DNA sequences to RNA and then to protein. The answers to the worksheet are also included. All of the information is provided as MS Word documents.
