Some DNA banks also store the DNA of rare or endangered species to ensure their survival. [1] The DNA bank can be used to compare and analyze DNA samples. Comparison of DNA samples allowed scientists to work on the Human Genome Project, which maps out many of the genes on human DNA. It has also led to the development of preventive genetics.

Epigenetic markers strengthen and weaken transcription of certain genes but do not affect the actual sequence of DNA nucleotides. DNA methylation is a major form of epigenetic control over gene expression and one of the most highly studied topics in epigenetics. During development, the human DNA methylation profile experiences dramatic changes.
Human evolutionary genetics studies how one human genome differs from another human genome, the evolutionary past that gave rise to the human genome, and its current effects. Differences between genomes have anthropological , medical , historical and forensic implications and applications.
A DNA database or DNA databank is a database of DNA profiles which can be used in the analysis of genetic diseases, genetic fingerprinting for criminology, or genetic genealogy. DNA databases may be public or private, the largest ones being national DNA databases. DNA databases are often employed in forensic investigations.

The International Nucleotide Sequence Database Collaboration (INSDC) consists of a joint effort to collect and disseminate databases containing DNA and RNA sequences. [1] It involves the following computerized databases : NIG 's DNA Data Bank of Japan ( Japan ), NCBI 's GenBank ( USA ) and the EMBL - EBI 's European Nucleotide Archive ( EMBL ).
