Mental retardation and epigenetics are also linked Epigenetic change can lead to the mutation of the FMR1 gene which controls cognitive functions. Fragile X syndrome is characterised by impaired cognition and autism. It mostly occurs in males with one X chromosomes but can occur in females as well. Scientist have linked very few diseases with epigenetic alteration and changes. These include: Obesity, Cancer, and
HOW DNA CAN BE MUTATED AND WHAT ARE THE SYSTEMS THAT CAN REPAIR BACK THE MUTATED DNA DNA mutation. Mutation are permanent heritable alteration in the base of sequence of DNA. Mutation occurs either because of spontaneous errors in DNA replication or in a meiotic recombination of as a consequence of the damaging effects of physical or chemical agents on the DNA.There are few concept in order to understanding mutation in DNA. It is known that DNA is a chemical compounds which the components are in an unique structures. The DNA molecules however can be modified, resulting in mutation.
If the state of ionization of amino acids in a protein is altered then the ionic bonds that help to determine the 3-D shape of the protein can be altered. This can lead to altered protein recognition or an enzyme might become inactive and denatured. Changes in pH may not only affect the shape of an enzyme but it may also change the shape or charge properties of the substrate so that either the substrate cannot bind to the active site or it cannot undergo catalysis. Several factors are influenced directly by the pH in which the reaction takes place. Extremely high or low pH values generally result in complete loss of activity for most enzymes.
Specific interventions provided by the Agri-Pinoy Rice Program are as follows: A. Production support • Production of Breeder Seeds of Inbred and Nucleus/Breeder Seeds of Hybrid Parentals • Basic Breeder Seed Production • Seed Production of varieties for climate change adaptation/mitigation; Including varieties that are submergence-tolerant, drought-tolerant/early maturing, saline-tolerant, and
After incubation period the embryos are allowed to germinate and sown to produce T1 seeds. These seeds are then ground and protein concentrations isolated by using an assay. Then a dilute series of recombinant LT-B and non-transgenic corn included in the assay, same is done with the TGEV. Production of the transgenic grain is then achieved by backcrossing lines of T1 seeds with commercial maize. Feeding trials then carried out.
It also comprise minerals such as potassium, phosphorus and calcium in reasonable amounts. Therefore, rice bran can be utilized substantially as a substrate without further addition. Rice husk used for enzyme manifacturing by solid state fermentation comparise cellulose (35%), hemicellulose (25%), and lignin (20%) and it is a good source of lignocellulosic biomass that may be used as rough material . For many these explanations solid state fermentation is approved as a encouraging technique for commercial scale assembly of α-amylase enzymes. Fungal sources have been found for α-Amylase assembly through submerged and solid state fermentation.
Genetic Modifications Genetic Modification is a change or substitution caused by human activity in the DNA (the substance that responsible about the appearance of the organism). Genetic modification was accomplished for the first time in 1973 by Stanley Cohen and Herbert Boyer. Some scientists in countries around the world aspire applying this technology on plants and humans. Now some countries like USA, Argentina, Brazil, Canada and China allow their scientists to make researches on genetic modification; which will allow unpredictable effects occur by this technology. Genetic engineering is a potentially and powerful very dangerous tool.
Insecticide resistance in rice planthoppers; influence, molecular mechanism and RNAi as future management Abstract: The evolution of insecticide resistance by insects threatens human welfare through its impact on crop protection and disease transmission. The number of insecticide-resistant species continues to increase worldwide, whereas insecticide resources are diminishing. Rice planthoppers developed resistance to different insecticides threat the success of pest control and resistance management. Thus, understanding the molecular basis of resistance mechanisms, including discovering the function of resistance-related genes, is critical to designing novel resistance management strategies, and developing new insecticidal compounds. Moreover,
Genetic modification has risen to the public eye as a highly controversial issue over the past few decades. Starting with the FLAVR SAVR tomato in 1994, we can now genetically alter any organism, including ourselves. We can, and have, manipulated crops to resist insects or herbicides and animals to glow in the dark, grow faster, change their color, or even make spider silk. However, out of the limitless applications of genetic modification, three in particular stand out as relevant to our everyday lives: genetically modified foods, gene therapy, and designer babies. Each of these has its root in the same basic technology, but comes with a unique set of pros and cons.
