Environment friendly and non polluting energy sources are called as Green Energy. These include solar energy, wind energy, geothermal energy, hydro energy etc. Nuclear power is also considered as a form of Green energy. These energy sources are considered as Green energy due to the fact that these forms of energy are less polluting since the carbon emission is too low.
Green Computing refers to the method of using environmentally sustainable computers and accessories. It aims to design, manufacturing, use and disposal of computers with minimum or no impact on the environment. The term Green IT is also used to describe the use of eco-friendly devices in Information Technology. Green computing aims to reduce hazardous chemicals in computer devices and to increase their energy efficiency. Green computing also promotes the recycling of electronic components and parts.
DNA Computing is the computational technology that uses the biomolecule DNA in the place of silicon based chips.DNA computing is otherwise known as the Bio molecular computing and is a fast growing interdisciplinary field that uses molecular biology and computer techniques in research and bio informatics areas.
Bio computing is the construction and use of computers that functions like living things or having biological components such as DNA. Bio computing is also used in bioinformatics to assist the biological research. Bio computing uses Bio computers which uses biologically derived molecules such as Proteins and DNA. These are used for computational calculations including data storage, data retrieve, data processing etc.
Endocrine disruptors are chemical substances that act on the endocrine system and disrupt its functions. The term Endocrine disruptor was introduced in the Wingspread Conference Centre; Wisconsin in 1991.The work of Theo Colborn showed that the environmental chemicals disturbed the development of endocrine system. Endocrine disruption refers to the fact that there is negative interference or permanent adverse consequences beyond the range of everyday fluctuations of hormone levels.
A gene is a set of instructions for making a molecule given through a set of nucleotides in a molecule of DNA or RNA, with most of the DNA existing on the 23 pairs of chromosomes in the nucleus of each human cell. The bases of the nucleotides are adenine, cytosine, guanine, and thymine which define the information in the gene and the molecular product, often a protein.
