Answer 1

Genomic sequencing

Question 2

The comparison of sequence data using statistics and computers

Answer 2

Bioinformatics

Question 3

Data used to study the evolutionary relatedness among groups of organisms

Answer 3

Phylogenetics

Question 4

Sequence divergence is used to estimate time since lineages diverged.

Answer 4

Molecular clocks

Question 5

The sequence of events during evolution can be determined using these sources of information.

Answer 5

Sequence data and fossil evidence

Question 6

The name given to the three broad groups of organisms

Answer 6

Domains

Question 7

Three domains of life

Answer 7

Bacteria, archaea and eukaryotes.

Question 8

Reveals that many of the same genes are found across different organisms

Answer 8

Conservation of genes

Question 9

The analysis of an individual’s genome which could lead to personalised medicine

Answer 9

Personal genomics

Question 10

Potential to treat individuals. Comes with difficulties as it is hard to distinguish between harmful and neutral mutations

Answer 10

Personalised medicine

Question 11

Species that are important in research

Answer 11

Model organisms

Question 12

Benefit of sequencing of disease-causing organisms.

Answer 12

Help with accurate diagnosis

Question 13

Benefit of sequencing pest species

Answer 13

Help identify risks and lead to specific methods of control being developed rather than general pesticides

Question 14

Benefit of sequencing of model organisms such as fruit flies, C. elegans nematodes or zebra fish.

Answer 14

Can be used in medical research in place of mammals (reducing ethical concerns and costs).
