3.8.3 Using genome projects

Question 1

What is DNA sequencing?

Answer 1

process to determine precise sequence of nucleotides in DNA

-synthesising many DNA fragments

Question 2

How can determine ing the genome of viruses could help develop a vaccine?

Answer 2

• identify proteome

- identify potential antigens to use in vaccines

Question 3

Why is it easier to sequence genome of simpler organisms?

Answer 3

• don’t contain introns (non coding)

Question 4

Why is it harder to sequence more complex organisms?

Answer 4

• contains introns

- more complex regulatory genes making it difficult to identify proteome
