Genetics is a branch of biology concerned with the study of genes, genetic variation, and heredity in living organisms.

What Were the Goals of the Human Genome Project?

The main goals of the Human Genome Project were to provide a complete and accurate sequence of the 3 billion DNA base pairs that make up the human genome and to find all of the estimated 20,000 to 25,000 human genes. ... read more »

What Did the Human Genome Project Accomplish?

In April 2003, researchers announced that the Human Genome Project had completed a high-quality sequence of essentially the entire human genome. This sequence closed the gaps from a working draft of the genome, which was published in 2001. ... read more »

What are the Next Steps in Genomic Research?

Discovering the sequence of the human genome was only the first step in understanding how the instructions coded in DNA lead to a functioning human being. The next stage of genomic research will begin to derive meaningful knowledge from the DNA sequence. ... read more »

What are Single Nucleotide Polymorphisms (SNPs)?

Single nucleotide polymorphisms, frequently called SNPs (pronounced'snips'), are the most common type of genetic variation among people.Each SNP represents a difference in a single DNA building block, called a nucleotide. ... read more »

What is the International HapMap Project?

The International HapMap Project is an international scientific effort to identify common genetic variations among people. This project represents a collaboration of scientists from public and private organizations in six countries. ... read more »

What is the Encyclopedia of DNA Elements (ENCODE) Project?

The ENCODE Project was planned as a follow-up to the Human Genome Project. The Human Genome Project sequenced the DNA that makes up the human genome; the ENCODE Project seeks to interpret this sequence. ... read more »

What are the Benefits of Genetic Testing?

Genetic testing has potential benefits whether the results are positive or negative for a gene mutation. Test results can provide a sense of relief from uncertainty and help people make informed decisions about managing their health care. ... read more »

What are the Risks and Limitations of Genetic Testing?

The physical risks associated with most genetic tests are very small, particularly for those tests that require only a blood sample or buccal smear (a procedure that samples cells from the inside surface of the cheek). ... read more »

What Advances are Being Made in DNA Sequencing?

Determining the order of DNA building blocks (nucleotides) in anindividual's genetic code, called DNA sequencing, has advanced the study of genetics and is one method used to test for genetic disorders. ... read more »

What is Genetic Discrimination?

Genetic discrimination occurs when people are treated differently by their employer or insurance company because they have a gene mutation that causes or increases the risk of an inherited disorder. ... read more »

What is Genetic Ancestry Testing?

Genetic ancestry testing, or genetic genealogy, is a way for people interested in family history (genealogy) to go beyond what they can learn from relatives or from historical documentation. ... read more »

What is Gene Therapy?

Gene therapy is an experimental technique that uses genes to treator prevent disease. In the future, this technique may allow doctors totreat a disorder by inserting a gene into a patient's cells instead ofusing drugs or surgery. ... read more »

What is Pharmacogenomics?

This relatively new field combines pharmacology (the science of drugs)and genomics (the study of genes and their functions) to developeffective, safe medications and doses that will be tailored to aperson's genetic makeup. ... read more »
