Genomic Sequencing (KA8)

Key Area 8

What happens in genomic sequencing

In genomic sequencing the sequence of nucleotide bases can be determined for individual genes and entire genomes

What are molecular clocks used to show

Molecular clocks are used to show when species diverged during evolution

What are personalised genomics

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

Pharmacogenetics the the use of

Genome information in the choice of drugs

What is required to determine the genomic sequence of an organism

Computer programmes and statistical analysis (bioinformatics)

Scientists compare the DNA base sequences of two different species and find that the sequences are very similar.

What does this suggest about the evolutionary relationship between the two species

That they last shared a common ancestor recently
