ASSESSING SAFETY OF GENETICALLY MODIFIED FOOD Introduction Today we use food that come from plants and animal modified by human through breeding, undergoing genetic changes from many thousand years. Plants and animals which have desire characteristics were chosen for breeding new generation. Desired characteristics arose from naturally occurring variations in genes of plants and animals. Hence genetic modification occurs naturally and forms the base of evolution. Techniques used today to modify genes

1. Introduction: Enzymes such as amylases, cellulases, xylanases and proteases are widely used in the industry for the manufacture of pharmaceuticals, foods, beverages and confectioneries as well as in textile and leather processing, and wastewater treatment. The potential applications of amylases, cellulases, xylanases and proteases in biotechnology have already been reviewed. The majority of the enzymes used in the industry are of microbial origin because microbial enzymes are relatively more stable

Fungi constitute a group of diverse eukaryotes which are only next to insects in terrestrial environments. About 1,28,432 species of fungi are known worldwide, while the existing global estimate of fungal species is 3 million, hence 95.72% remains yet to be described. Mushrooms are distinctive spore producing fruiting bodies which can be either epigenous or hypogenous and large enough to be seen with the naked eye and to be picked by hand. Mushrooms are variously called macrofungi, macromycetes,

Shannon L. Alder, the author of "300 Questions to Ask Your Parents Before It is Too Late" claims: "Peer pressure has the power to create a diamond, but it has to be the "right" pressure". This quotation means that there are both positive and negative pressure in today's world. It can influence a human to do something that is quite harmless, or something that has more critical results. Positive peer pressure is when people inspire us to study by heart, join activities such as playing football, volleyball

chromosomes can be defined as a very long thread-like strands of DNA and associated proteins in nucleus of cell, that carry part (or all) of the genetic materials and function in transmission hereditary information. In G1 phase, the chromosomes are extremely fine and called as chromatin. At this phase, the cell will decide whether or not divides and then completes the cycle to form new cell. Next, at S phase, the genetic material (DNA) undergoes replication. The duplication of two chromosomes consist

“Forensic anthropologist usually works in three broad categories,” said Texas State professor Jerry Melbye.” A Forensic Anthropologist help examine a human skeletal or decomposed remains in a legal setting to establish the identity of an unknown individual and to help determine the cause of death.A Forensic Anthropology work to find the individual that was murdered or was a homicide.They need to find the biological profile of that person.They have many ways to find a biological profile.A biological

The History of Criminal Investigations DNA Overturned June 29, 2016 Many cases have been solved with good investigation work and the technology of DNA. As a result of this technology many convicted criminals have been released due to DNA overturned in their cases. This was true in the case of Anthony Capozzi who spent 22 years in prison for a crime

DNA Worksheet REVISED Part1: Basic structure of DNA The nucleotide bases of a DNA consists of specific codes and particular strands of this codes are known as the genes. The genes codes for a particular protein which eventually be a specific trait. The pairing of the base in a DNA molecule is very specific. Adenine usually pairs with Thymine while Guanine normally pairs with Cytosine. A segment of a gene from DNA usually gives the necessary directions to build a RNA molecule and eventually translated
