Genetic predisposition

Are we humans perfectly fitted to the world we live in today? Evolutionary psychology suggests this may not be the case. An important concept in evolutionary psychology is mismatch (link is external) (1). Evolutionary mismatch occurs when the environment that organisms are adapted to, via a slow process of biological evolution, changes so quickly and intensely that it hinders these organisms to fulfill their reproductive needs. Take an example from nature. Deforestation has changed the habitats…

PCR (Polymerase chain reaction) Polymerase chain reaction (PCR) is a laboratory method that is used to form number of copies of a specific region of DNA interested in. The principle of the polymerase chain reaction is based on the natural replication process of DNA and complementary nucleic acid hybridization. The goal of the PCR is to produce required amount of the target DNA region that is be analyzed. PCR amplified DNA is sent for sequencing and visualized by gel electrophoresis. It also can…

species that stay in that environment and use it as their habitat adapt to the changes of the environment to survive the changes and their off springs are also able to survive. This happens because the species staying in that environment change their genetic make-up in order to accommodate themselves and these changes are passed on to the off springs and the off springs are immune to the changes. The species that are unable…

In order to evaluate the efficiency of RAPD-PCR fingerprinting for Cajanus cajan L. cultivar, the DNA templates for 7 RAPD primers banding modality were used. The total number of magnified fragments in the Cajanus cajan L. cultivar value of each primer was represented in Table 2. Total of 18 bands were obtained for all primers. The size of the amplified bands was ranged between 1000 bp and 300 bp. Primers OP-A5, OP-B4, OP-B9, OP-C5 and OP-E15 showed at least three specific fragments. Primer…

Methylation is a key biochemical process that is essential for the proper functioning of almost every system in your body. It occurs billions of times per second; it helps repair your DNA on a daily basis; it controls homocysteine (an unhealthy compound that can damage blood vessels); it allows the recycling of molecules necessary for detoxification; and it helps maintain mood and keep inflammation under control. To maintain the proper functioning of methylation you need an optimal level of…

organelles, it preserves its DNA in the cytoplasm where the replication takes place as well. Their rich cousins, however, the swanky eukaryotes, are far more elegant and ostentatious. Within theirs membrane, they have a variety of organelles, including a genetic “godown,” the nucleus, where the DNA is stored and sequestered (BiologyWise,…

1. ABSTRACT: A total of 552 serum samples of sheep, goats and cattle from different localities at Assiut governorate, Egypt were screened for qualitative analysis of the BTV antibodies using a commercial competitive ELISA (cELISA) kit. The results showed an overall percentage of BTV positive sheep, goats and cattle serum samples were 41.86%, 24% and 85.42% respectively. A highest percentage of seropositivity was found in Arab El- Awamer farm(100%), followed by Abnoub( 63. 64%), Sedfa(11.…

GENE REGULATION: Gene regulation is the method of limiting the genes in the cell’s DNA, which are expressed. It is utilize to form a functional manufacture for an example protein. Various cells in a multi cellular organism might express very difficult group of genes. Although, they consist the similar DNA. Human having over ten thousands of genes in their genome. Cells are expressed the all genes. Even an organism as simple as bacterium must carefully regulate gene expression. Ensuring that the…

affect an individual’s response to drugs. This is a new field that combines pharmacology (the science of drugs) and genomics (the study of genes and their functions) to develop fruitful, safe medicines and doses that will be customized to a human genetic makeup. Now drugs that are available are “one size fits all,” but they do not effective for every person. It is very tough to augur that a person get benefit from drug or not, and whether the drug has a side effects .Negative side effects of…

In modern molecular biology and genetics, the genome is the genetic material of an organism. It consists of DNA (or RNA in RNA viruses). The genome includes both the genes and the non-coding sequences of the DNA/RNA. Understanding Human Genetic Variation Genetics is the scientific study of inherited variation. Human genetics, then, is the scientific study of inherited human variation. We study genetic material due to following reasons; 1. One reason is simply an interest in better understanding…
