1.8 genomic sequencing

Question 1

Define genomics

Answer 1

Genomics is the study of genomes

Question 2

What is bioinformatics

Answer 2

Bioinformatics stores, displays, compares and analyses different sequences from DNA, allowing scientists to rapidly map out DNA sequences

Question 3

Define & explain phylogenetics

Answer 3

• is the study of revolutionary history and relationships

- uses sequence data to identify evolutionary relatedness

Question 3

Define & explain phylogenetics

Answer 3

• is the study of revolutionary history and relationships

- uses sequence data to identify evolutionary relatedness

Question 4

Define molecular clocks

Answer 4

Uses mutation rate to calculate the time when 2 or more different life form separated through evolution

Question 5

What does a molecular clock show

Answer 5

Shows differences in DNA or amino acid sequences to indicate a length of time species diverged from their common ancestor

Question 6

What are the 3 domains of life

Answer 6

• bacteria
• archaea
• eukaryotes

Question 7

Define personal genomics

Answer 7

An individuals genome can be analysed to predict the likelihood of developing certain disease

Question 8

What is pharmacogenetics

Answer 8

The use of the genome to choose the correct drugs for treating an individual as drugs work differently based off someone’s DNA

Question 9

What are the benefits of pharmacogenetics

Answer 9

• correct drug can be given to treat the individual

- correct dosage can be given to treat the individual
