Genomics is a branch of genetics that studies genomes, which are the complete set of DNA in an organism, including all of its genes. Genomics focuses on analyzing the structure and function of the genome, and how genetic changes affect an organism’s health and behavior. This specialty overlaps with many other fields such as molecular biology, biotechnology, medical genetics, and bioinformatics.

Fields of study in genomics:
Structural genomics:

• Genomic sequencing: determining the sequence of nitrogenous bases in the genome.
• Gene identification: identifying the locations of genes and the potential functions of each.

Functional genomics:

• Gene expression: The study of how genes are expressed and genetic information is converted into proteins.
• Gene interactions: Understanding how genes interact with each other and with environmental factors.

Comparative genomics:

• Comparing genomes: studying the differences and similarities between the genomes of different species.
• Genome Evolution: Understanding how genomes have evolved over time and how evolution affects biodiversity.

Medical genomics:

• Medical genomics: using genetic information to diagnose and treat diseases.
• Clinical genomics: The application of genomic technologies in clinical medicine to improve health care.

Bioinformatics:

• Genomic data analysis: Using computational tools to analyze and interpret genomic data.
• Algorithm development: Creating algorithms and models to effectively analyze genomic data.
