3.8.3 Using genome projects

Question 1

Genome methods development summary

Answer 1

• continually being improved
• now automated

Question 2

Why is it easier and useful to genetically sequence simple organisms?

Answer 2

• eg prokaryotic cells
• don’t contain introns in their DNA
• genome can be used to directly sequence the proteome of the organism
• useful to identify potential antigens to use in a vaccine

Question 3

Why is it harder to sequence the genome and proteome in complex organisms

Answer 3

• contain introns and regulatory genes in DNA
• genome can’t easily be translated to proteome

Question 4

Why is it useful to determine the genome of a bacteria or virus

Answer 4

• could identify the proteome
• which could identify antigens that can be used in vaccines
