Genomics

Question 1

What is genomics?

Answer 1

The study of the sequence of bases in DNA called the sequence data.

Question 2

What is genomics undertaken on?

Answer 2

The sequence data of pathogens (disease causing organisms e.g. MRSA) and pests in food crops (e.g. greenfly etc.)

Question 3

What is bioinformatics?

Answer 3

The comparison of sequence data using computer and statistical tests.

Question 4

What is phylogenetics?

Answer 4

Needs sequence data and fossil data to study evolutionary relatedness.
Gives an estimate of time since divergence from common ancestor.
More closely related species are more similar in sequence data- diverged later in time.

Question 5

What are the 3 domains of life?

Answer 5

Bacteria
Archaea
Eukaryotes

Question 6

What is evolution of life?

Answer 6

The more related the species, the closer the sequence data.
Many genes are conserved across different species due to common ancestor.

Question 7

What are molecular clocks?

Answer 7

Graph showing how many amino acids differ (derived from sequence data) since we have a common ancestor. Also use fossil data.

Question 8

What are pharmacogenetics?

Answer 8

Drugs designed to be suit individuals with certain sequence data.
