Introduction

How does DNA determine what an organism looks like? Why is genetic diversity important? Here you will review how DNA codes for proteins, which determines what an organism looks like and how it contributes to genetic diversity and why this is important for evolution. Use the video resources on the Resurrection Science student esheet to help you answer the questions on this sheet.


1. Draw the central dogma for how DNA makes protein below.

 

2. Define genotype and phenotype. Which part of the central dogma above represents the genotype and which represents the phenotype?  

 

3. Define gene and allele. Where are genes found? Where are alleles found?

 

4. What is heredity? How many chromosomes do you get from each parent?

 

5. What does genetic diversity mean? Why is this important for natural selection and evolution?

 

6. In your own words, briefly describe CRISPR-Cas9 and one genetics application it can be used for.
