The DNA Learning Center (DNALC) is a genetics learning center affiliated with the Cold Spring Harbor Laboratory, in Cold Spring Harbor, New York.It is the world's first science center devoted entirely to genetics education and offers online education, class field trips, student summer day camps, and teacher training.

DNA profiling was developed in 1984 by British geneticist Sir Alec Jeffreys, [166] and first used in forensic science to convict Colin Pitchfork in the 1988 Enderby murders case. [167] The development of forensic science and the ability to now obtain genetic matching on minute samples of blood, skin, saliva, or hair has led to re-examining many ...
The DNA model shown (far right) is a space-filling, or CPK, model of the DNA double helix. Animated molecular models, such as the wire, or skeletal, type shown at the top of this article, allow one to visually explore the three-dimensional (3D) structure of DNA. Another type of DNA model is the space-filling, or CPK, model.
DNA is made of simple units that line up in a particular order within it, carrying genetic information. The language used by DNA is called genetic code, which lets organisms read the information in the genes. This information is the instructions for the construction and operation of a living organism.
Genetic disorders can be caused by any or all known types of sequence variation. To molecularly characterize a new genetic disorder, it is necessary to establish a causal link between a particular genomic sequence variant and the clinical disease under investigation. Such studies constitute the realm of human molecular genetics.

The transferred DNA is piloted to the plant cell nucleus and integrated into the host plants genomic DNA.The plasmid T-DNA is integrated semi-randomly into the genome of the host cell. [ 23 ] By modifying the plasmid to express the gene of interest, researchers can insert their chosen gene stably into the plants genome.
