Genetic code

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…

of this step to separate or to denature the DNA strands by heating the reaction strongly. This provides single-stranded template for the next step. This is carried at a temperature of 900c (1940F) to break the bonds between nucleotides forming DNA code ensuring the accessibility of the gene of…

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.…

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…

There are roughly thirty-seven trillion cells present in the human body. Each of these cells have a specific function to perform like propagating one’s genes or carrying oxygen towards the different parts of the body. Some of these cells make up the skeletal system which is comprised of two hundred and seven different bones. Some of these cells make up the various organs in the body like the lungs and the heart. Some of these cells are responsible for the organs responsible for procreation, the…

This article looks at the seismonastic response (the response of a plant to touch or vibration) and how it utilizes the transport of K+ in the pulvinar cells (the thickening at the base of a leaflet that causes the movement of the leaflet based on differing turgor pressure in these cells). They tested many hypotheses regarding the seismonastic reaction in the Mimosa pudica, one of which tested whether there was an increased efflux of K+ from pulvinar cells during stimulation. The experimenters…
