Genetics is the study of genes, genetic variation, and hereditary in living organisms. In DNA A always pairs with T. DNA is the blueprint of life. Humans have 46 chromosomes. Our entire DNA sequence is is called a genome. The average gene is 10,000 to 15,000 bases long. DNA can be extracted from many different types of samples: blood, cheek cells, urine. Alleles are forms of of the same gene with small differences in their sequence of DNA bases. Genes are made up of DNA. There are about 20,000 important genes located on one of the 23 chromosome pairs found in the nucleus or on long strands of DNA located in the mitochondria. A genetic disorder is a disease that is caused by an abnormality in an individual's DNA. Abnormalities can be as small

Gene therapy could be a way to fix a genetic problem strong at its source. By adding a corrected copy of a defective gene, gene therapy promises to help diseased tissues and organs work properly. This approach is different from traditional drug based approaches, which may treat symptoms but not the underlying genetic problems. Gene therapy is the transplanation of normal genes into cells in place of missing or defective ones in order to correct genetic disorders. Gene therapy uses a vector, typically a virus to deliver a gene to the cells where it's needed. Once it's inside, the cell's gene reading machinery uses the information in the gene to build RNA and protein molecules. The proteins, RNA can then carry out their job in the cells. Gene therapy is an experimental technique that uses genes to treat or prevent disease. In the future, this technique may allow doctors to treat a disorder by inserting a gene into a patient's cells instead of using drugs or surgery. The father of genetics is Gregor Mendel, a late 19th century scientist and Augustinian friar. Mendel studied "trait inheritance," patterns in the way traits are handed down from parents to offspring. Genetic processes work in combinations with an organisms environment and experiences to influence development and behavior often referred to as nature versus
