Such a quadruplex is described as tetramolecular, reflecting the requirement of four separate strands. The term G4 DNA was originally reserved for these tetramolecular structures that might play a role in meiosis. [5] However, as currently used in molecular biology, the term G4 can mean G-quadruplexes of any molecularity.
DNAzyme research for the treatment of cancer is also underway. The development of a 10-23 DNAzyme that can block the expression of IGF-I (Insulin-like growth factor I, a contributor to normal cell growth as well as tumorigenesis) by targeting its mRNA could be useful for blocking the secretion of IGF-I from prostate storm primary cells ...
The institute was established in 1955 to conduct scientific research into the physiology and nutrition of farm animals. The founder of the institute and its first director was Jan Kielanowski, whose name was given to the institute in 1990. [3] Institute directors: Jan Kielanowski (1955–1974) Stanisław Buraczewski (1974–1986)
A monogastric digestive system works as soon as the food enters the mouth. Saliva moistens the food and begins the digestive process. (Note that horses have no (or negligible amounts of) amylase in their saliva). After being swallowed, the food passes from the esophagus into the stomach, where stomach acid and enzymes help to break down the food.
For all animals, some amino acids are essential (an animal cannot produce them internally) and some are non-essential (the animal can produce them from other nitrogen-containing compounds). A diet that contains adequate amounts of amino acids (especially those that are essential) is particularly important in some situations: during early ...
Primary nutritional groups are groups of organisms, divided in relation to the nutrition mode according to the sources of energy and carbon, needed for living, growth and reproduction. The sources of energy can be light or chemical compounds; the sources of carbon can be of organic or inorganic origin.
A typical course would study the metabolism of proteins, carbohydrates, lipids, minerals, vitamins and water, and the relationship between these nutrients and animal production. [1] A Master's degree in nutrition is often seen in animal nutrition and the field requires a Ph.D. in the science of nutrition. [2]
According to EU Regulation 1831/2003, [9] all feed additives to be placed on the market within the European Union have to undergo a thorough approval process. Those who seek approval for the products as livestock food additives must submit them to the European Food Safety Authority (EFSA), the European Reference Laboratory, the European Commission and the member states.
