Biocomputing and computational biology are synonymous and Biocomputing and computational biology are synonymous and

describe the use of computers and computational techniques to describe the use of computers and computational techniques to

analyze any biological system, from molecules, through cells, analyze any biological system, from molecules, through cells,

tissues, organisms, and populations, to complete ecologies.tissues, organisms, and populations, to complete ecologies.

Bioinformatics describes using computational techniques to access, Bioinformatics describes using computational techniques to access,

analyze, and interpret the biological information in any of the analyze, and interpret the biological information in any of the

available online biological databases.available online biological databases.

Sequence analysis is the study of molecular sequence data for the Sequence analysis is the study of molecular sequence data for the

Genomics analyzes the context of genes or complete genomes (the Genomics analyzes the context of genes or complete genomes (the

Proteomics is a subdivision of genomics concerned with analyzing Proteomics is a subdivision of genomics concerned with analyzing
