The Foundation of Biochemistry

Molecular Anatomy Reveals Evolutionary Relatio The naturalist Carolus Linnaeus of the XVIII Gin of different types from a common ancestor. Biochemical research in the 20th century revealed the molecular anatomy of cells of different species, the sequences of monomeric subunits, and the three-dimensional structures of individual nucleic acids and proteins.

There are three different spheres of life

All living organisms fall into one of the three great groups (kingdoms or domains) that define three branches of evolution from a common ancestor (Fig. 14). For biochemical reasons, two large groups of prokaryotes can be distinguished: archaebacteria (from the Greek arche, “ori gin”) and eubacteria (again from the Greek […]

Cellular Foundations

The unity and diversity of organisms become apparent even at the cellular level. The smallest organisms consist of single cells and are microscopic. Larger, multicellular organisms contain many different types of cells, which vary in size, shape, and specialized function. Despite these obvious differences, all cells of the simplest and […]

polymerase Chain Reaction

It is a revolutionary method developed by Kary Mullis in the 1980s. PCR is based on the use of the ability of DNA polymerase to synthesize a new DNA strand that is complementary to the offered template strand. Since DNA polymerase can only add one nucleotide to an already existing […]

Pesticides are the gathering of synthetics or substance plans utilized in horticulture for shielding yields or crop items from the danger of nuisances, creepy crawlies, spices, weeds and organism etc. A significant number of these agrochemicals are accounted for to be cancer-causing in lab creatures. Epidemiological confirmations of cancer-causing impacts […]

Toxicology and its effects

Toxicology deals with the science of poisons. Chemicals/substances which are toxic in nature are present in the environment and find their way to the organisms through food chain, contact or respiration. The lower doses of these chemicals get accumulated in the body tissues and impair the growth/function while their higher […]

Ecological Organization of Organisms

All organisms are interdependent and interrelated with one another and with their environment. This concept applies at all levels from a small pond to the world. Implicit in ecological organization is the idea that plants and animals do not occur randomly, but rather that particular kinds are especially adapted to […]

Science and scientists

science is an attitude. or a way of looking at things, which arose out of man’s intellectual curiosity. The first humanoid creature that stood on a seashore and observed that the water level rose and fell with the regularity and asked himself what caused this was exhibiting a basic mark […]
