This organism is widespread in the environment, but rare in the flora of healthy individuals. Its carriage increases with hospitalization.
Structural bioinformatics is concerned with computational approaches to predict and analyse the spatial structure of proteins and nucleic acids.
In botany, a herbarium is a collection of preserved plant specimens. These specimens may be whole plants or plant parts: these will usually be in a dried form, mounted on a sheet, but depending upon the material may also be kept in alcohol or other preser
Germplasm theory of Weismann was a very significant advancement in our understanding of heredity, since this was for the first time that a distinction between hereditary and environmental variations could be made on a sound basis.
The area of developmental genetics has also received major attention of geneticists in recent years to answer questions like the following. What are the relative roles of nucleus and cytoplasm in differentiation?
Plants appeared on land about 425 million years ago and the evolutionary history of the plant kingdom reflects increasing adaptation to the terrestrial environment. Plants have organs and organ systems.
A bacteriophage is a virus that infects bacteria. Like all viruses, phages are obligate intracellular parasites, devoid of protein synthesizing machinery and energy conversion systems.
The biosphere as usually defined is the thin outer layer of the earth capable of supporting life. It is probably best viewed as a global system that includes all life on earth and the physical environments in which living organisms exist and interact.
Protiens are polymers of amino acids joined by peptide bonds (proteins are therefore also known as polypeptides). The number and order of the amino acids contained in a particular protein are prescribed by the DNA sequence of that protein?s gene.
The most important areas of today's research which have potential economic value and prospects of commercialization are the cell and tissue culture based production of vaccines, monoclonal antibodies, pharmaceutical drugs, cancer research, genetic manipul
The flower has acquired an unique position in our lives. Floriculture deals with growing or cultivation (large scale) of beautiful flowering plants.
A tree is a perennial woody plant. It is most often defined as a woody plant that has many secondary branches supported clear of the ground on a single main stem or trunk with clear apical dominance.
The Chloroflexi (Chlorobacteria) are a class of bacteria that produce energy through photosynthesis. They make up the bulk of the filamentous anoxygenic phototrophs
An amalgamation of the term biological energetics, is the branch of biology and biochemistry that is concerned with how organisms extract energy from their environment and with how energy is used to fuel the myriad of life?s endergonic processes.
Atoms of certain metals will absorb and emit radiation of specific wavelengths when heated in a flame, in direct proportion to the number of atoms present.
Mutations are heritable changes in the genetic material that give rise to alternative forms of any gene. These alternate forms are called alleles. There are two broad types of mutations, those that affect the gene and those that affect whole chromosomes (
