GI: DNA Technology, Classification and Diversity

Question 1

What 3 technological advancements can be used to clarify evolutionary relationships?

Answer 1

Genome sequencing

Comparing amino acid sequences

Immunological comparisons

Question 2

How can genome sequencing be used to clarify evolutionary relationships?

Answer 2

• Base sequences of individuals can be compared
• Closely related species will have higher percentage of similarity in DNA base order

Question 3

How can comparing amino acid sequences be used to clarify evolutionary relationships?

Answer 3

• Related organisms have similar DNA sequences and so similar amino acid sequences.

Question 4

How can immunological comparisons be used to clarify evolutionary relationships?

Answer 4

• Similar proteins will bind to the same antibodies

Question 5

Early estimates of genetic diversity were made using what?

Answer 5

Looking the frequency of measurable or observable characteristics.
