Review of literature Tomato is one of the important crops of family Solanaceae and is widely cultivated in tropical, sub-tropical and temperate climates. It holds second ranks in terms of world vegetable production after potato (FAO 2006). Tomatoes have been used as food by the population of Central and South Americas since prehistoric times (Choudhoury, 1967). All tomato varieties in Asia and Europe are supposed to be descendants of the seeds taken from Latin America to Europe and Asia by the Spanish

Matrix metalloproteinases (MMPs) contribute to curing by acting as proteinases that degrade the extracellular matrix and regulate the activity of signaling molecules and growth factors (1). Proteases classified into 4 types including serine proteases, cysteine proteases, aspartate proteases and metalloproteases based on their remainder or cofactor fundamental in catalysis. A metalloproteinase, is any protease enzyme whose catalytic mechanism involves a metal. Most metalloproteases require zinc,

the smallest bacteria can move away or toward chemicals. Movement toward this is considered a good response, while movement away from this is considered a negative response. The single celled creatures or organisms multiply by duplicating their DNA. They then divide equally as the cell prepares to divide to form two new cells. The multicellular creatures or organisms produce reproductive germline cells that form new individual cells. When the reproduction

easy way to increase yields. The transgenic cows exist that produce more milk or milk with less lactose or cholesterol. Some of the disadvantages of transgenic plants and animals are; GMO have been known to retain some of the genetically modified DNA in products made for human consumption. These remnants of genetic material are harmful to human health that can cause allergens. GMO have the potential to replace traditional farming or poultry and meat producing which can result in destruction of

OBJECTIVE: To develop an understanding of bacterial transformation by plasmid DNA, and determine the transformation efficiency of a bacterial sample. INTRODUCTION: Transformation is an important biological mechanism for generating genetic diversity in the natural world. It is also one of the most used tools used in modern biotechnology. It has allowed for a lot of genetic engineering advances. Scientists can design and build DNA containing genes they want and then transfer these genes into bacterial

NAME: ROLL NO: Section: CASE STUDY- GENETICALLY ENGINEERED CROPS: The growing of genetically engineered (GE) crops is something that Greenpeace has long opposed, due to the risks posed to both human health and the environment, and unwanted contamination of our food due to the difficulties of controlling the spread of these crops. In recent months, news has emerged about how chemical and pharmaceutical giant Bayer has been forced to make massive payouts after conventional US rice crops were

Ethics, What is it? Merriam-Websters dictionary defines it as “The discipline dealing with what is good and bad with moral duty and obligations.” Yet, if we look at many of the things we take for granted today, they remain available to us because of certain unethical and immoral activities that occur. Lets look at two very controversial issues that have come up today; water boarding and genetic engineering. Is water boarding a form of torture or not? Both sides bring a valid argument to the table

that we may have breakthroughs in devastating human diseases? Caught your attention yet? January 2014, Chinese scientist had successfully created genetically modified monkeys using a new procedure that literally allows scientist to cut-and-paste DNA into living organisms. The two macaques were the first primates to ever have their genetic makeup altered. Though not without backlash, as animal rights activist considered such a feat inhumane. The means of which this was done was through a genome

PTC Taster Genomic Analysis Lab Report Laboratory Goals: 1. Determine Taster Phenotype 2. Isolate DNA from each individual 3. Determine Taster Genotype Hypothesis: If I am a taster, then my genotype for PTC taster must be either TT (homozygous dominant) or Tt (heterozygous) I – Results: This experiment aimed to investigate the allele frequency of the PTC taster gene (TAS2R38) in a small population, represented by the students in class. The genotype obtained from genomic
