Genomics

Genetics vs genomics

Genetics

• The study of how genes work and their inheritance

Genomics

• The study and mapping of genomes (entire sets of DNA)

The human genome

• Approximately 3.2 billion nucleotides of DNA   * The sequence of bases can be found through DNA sequencing     * The sequence can then be compared to a reference genome

Types of genomics

Structural

• Aims to determine the structure of every protein encoded by the genome

Functional

• Uses DNA sequence to describe/predict gene and protein function

Comparative

• Compare genomic features between different species

Mutation

• Studies the effects of mutations or variants throughout genomes   * Variants are an alteration in the most common DNA nucleotide sequence

Uses of genomics

• Understand the structure and function of whole genomes
• Evaluate the effects of mutations/variants
• Mapping location, structure, and function of every gene and other important sequences
