Don’t we already know how this movie’s going to end? In a potentially terrifying case of life imitating art, the renowned paleontologist who served as the inspiration for Jurassic Park protagonist Dr. Alan Grant is spearheading genetic research that could engineer dinosaurs back into existence …
Current researches are optimistic on the potentials of nanotechnology as the latest technological wonders with both environmental soundness and promise for health applications. Its advent has created promising application in various areas of human endeavors. It has made impression in the areas of novel foods, …
Introduction Once absorbed, active elements of vitamin D, such as calcitriol, attach themselves to intracellular receptors and then act as transcription factors so as to modulate gene expression (Holick, 2010). The vitamin D receptors are similar to thyroid hormones and steroid hormones receptors and contain …
Rauch, in the beginning of his article, points out several potential merits of agricultural biotechnology such production of transgenic seeds which can counteract the effects of herbicides (2003). This could facilitate no-till farming since the use of herbicides can curtail the growth of weeds. The …
Base pairs: always occur in a specific way – A(adenine) always pairs with T(thymine) and C(cytosine) always pairs with (G)guanine. Because of this specific base pairing, the base sequence of one DNA strand determines the base sequence of the other strand. Genetic code: the set …
Proteun characterization by electrophoresis Abstract The molecular weights of protein extracts were assessed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Two sets of four protein samples, standard bovine serum albumin (BSA), invertase, egg albumin, and casein, were prepared; one set containing ? -mercaptoethanol (BME) while …
Introduction Literature It is highly expressed in pain-sensing neurons which are of two types, the nociceptive dorsal root ganglion (DRG) neurons, and sympathetic ganglion neurons, which are parts of the autonomic (involuntary) nervous system (Cox et al, 2006). In human’s mutation in SCN9A cause three …
A genetically designed potato could be a potato that has had its genes changed, exploiting recombinant DNA technology. Objectives of modification contain presenting pest-fighting, amendment of the number of some chemicals fashioned by the plant, and to avoid staining of the potatoes. Multiplicities changed to …
Animal and plant cells have many of the same characteristic. Animal cells and plant cells are both eukaryotes. They both have cell nucleus which contain chromosomes or DNA, as well as cell membrane encompassing the cell to control the substances moving in and out of …
Agriculture – the study of producing crops from the land, with an emphasis on practical applications Anatomy – the study of form and function, in plants, animals, and other organisms, or specifically in humans Arachnology – the study of arachnids (more…)
The main purpose of this paper is to explain how the division of cells is highly regulated such that cells that fail to pass some specific stage-based tests cannot advance to the proceeding stages. Basically, the cycle is directly attached to some bioenergetic and biosynthetic …
Introduction A cell’s plasma membrane is known to be selectively permeable. This implies that the membrane is selective on what substances can pass in and out of the cell. There are two methods of transport that occur through the plasma membrane. One method of transport …
With root cell therapy scientists hope to bring around diseases and replace damaged tissues and variety meats in the human organic structure. Stem cell research for the possible application of cell based therapy in dental medicine has incited a considerable sum of exhilaration. At present …
Introduction Bacterial resistance to antibiotics is a global problem in the treatment of bacterial infection.

Four categories
What Are The 4 Types Of Biotechnology? The four main types of biotechnology are medical biotechnology (red), industrial biotechnology (white), environmental biotechnology (green), and marine biotechnology (blue).
Education
After graduating from high school, an aspiring biotechnologist typically needs to earn a bachelor's degree. While it is possible to pursue this career with an undergraduate degree in one of the life sciences or a related area of engineering, the most linear pathway is to major in biotechnology itself.
Technology
Biotechnology is technology that utilizes biological systems, living organisms or parts of this to develop or create different products. Brewing and baking bread are examples of processes that fall within the concept of biotechnology (use of yeast (= living organism) to produce the desired product).
