Evolution

Question 1

DNA Hybridisation

Answer 1

1. Take DNA from two species
2. Heat DNA to 95°, separates into single strands
3. Mix them together & then cool
4. To determine how related the speces are, “hybrid” double Stranded DNA is heated. The hotter the temp required to break H bonds between stands, the more H bonds there must be.
   Meaning there are more complementary bases & the bases are more closely related.
