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.
Genetics is a discipline of biology. It studies the hereditary and genetic issues that have deep impact on the appearance, health and behaviour of an individual.
Human genetics is the study of heredity. It actually discusses the human genome and relates it with inherited characteristics
Deoxyribonucleic acid; A nucleic acid which carries genetic information inside of the cell. It is capable of synthesis and self-replication of RNA. DNA consists of two long chains of nucleotides which are twisted into a double helix and joined by hydrogen bonds. The sequence of nucleotides helps to determine 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.
Gene testing is a process of examining one’s DNA by taking a sample from cells in the blood, in body fluids or tissues.Genetic tests are used to observe or determine genetic disorders a person may possess.
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.
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.
There are many diseases whose roots can be traced to the genetic make-up of the human beings. A majority of the genetic conditions and the resultant disorders are inherited from the parents.
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
Genetics and biotechnology have come forward in leaps and bounds as our understanding the genome and genetics increases. Over the last decades DNA has been mapped, manipulated and studied. These studies are sometimes on the chemical, molecular microscopic level
A Genetic Counsellor must be knowledgeable with the current genetic diseases and how these diseases affect the daily lives of an individual. This person must be able to understand the risks involved in acquiring certain genetic disorders. Also, the counselor should know how these diseases may appear in the line of one’s family.
The science and technology of building electronic circuits and devices from single atoms and molecules.
Dimples are considered mark of beauty and loveliness. The truth is that dimples are actually genetic defects that are caused by shortened facial muscles.
