A hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism by directing the formation of a specific protein, and is capable of replicating itself at each cell division. Genes undergo mutation when their DNA sequence changes.
Deoxyribonucleic acid; A nucleic acid that carries the genetic information in the cell and is capable of self-replication and synthesis of RNA. DNA consists of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds. The sequence of nucleotides determines individual hereditary characteristics. All about DNA
DNA is made up of subunits called nucleotides. Each nucleotide is made up of a sugar, a phosphate and a base.
Ribonucleic acid; A long linear polymer of nucleotides found in the nucleus but mainly in the cytoplasm of a cell where it is associated with microsomes; it transmits genetic information from DNA to the cytoplasm and controls certain chemical processes in the cell. Ribonucleic acid is the genetic material of some viruses.
An individual's unique sequence of DNA base pairs, determined by exposing a sample of the person's DNA to molecular probes. DNA fingerprints are often used as evidence in criminal law cases.
A paternity test can be conducted to prove whether or not a man is the biological father of another individual. The comparison of secific DNA sequences of two individuals can prove whether or not the genetic material of one individual was derived from that of the other. All about Paternity Test
A circular strand of DNA in bacteria that contains the hereditary information necessary for cell life.
Any defect or disorder in the mutation in DNA of one gene or a gross defect in entire set of chromosomes in Genome leads to genetic diseases, which can vary from minor to major genetic defects or diseases.
Techniques of genetics and biotechnology used to cut up and join together genetic material and especially DNA from one or more species of organism and to introduce the result into an organism in order to change one or more of its characteristics
The science and technology of building electronic circuits and devices from single atoms and molecules.
