With each passing minute, the world population increases by hundreds, and to support the ever-increasing population, food is required. To cope up with this food demand, various methods are being devised since decades. A recent one under discussion is ‘Gene Editing’. This method, unlike any…
Amongst the rapidly growing field of genetics lies a rather peculiar process which once was the pinnacle of Science Fiction now a certain absolute in reality – Cloning. Regardless of any controversial issues surrounding this process, it is now more widely used than ever and…
Homosexuality known as a sexual desire and attraction to individuals of one’s possess sex. The term gay is regularly utilized as an equivalent word for gay person; female homosexuality is frequently called as lesbianism. The geneticists had found that genetic factors may influence the homosexuality…
The article I chose to write about for the second writing assignment focuses on Scinax treefrogs in south-eastern Brazil and how sea level incursions has shaped their genetic differentiation. I chose to write about this paper because I find it interesting how species near each…
GMOs are transgenic organisms carrying foreign genes either from virus, bacteria, plants, humans in order to improve their genetic structure for particular purposes. In this procedure the beneficial or gene of interest is identified which is then isolated and multiplied and then inserted into the…
Salmonella bacteria is a rod-shape motile bacterium. Its structure contains: Flagellum tail-like structure that allows the bacteria to swim/move around in liquid environment by moving the tail in wave motion. Cell wall that allows the bacteria to keep its shape rounded tube shape. DNA contains…
Researchers from Stanford University School of Medicine and the Palo Alto Veteran Affairs Health Care System have established a section of genetic mutations which govern cholesterol levels in the body and may also guide the development and use of cardiovascular and diabetes drugs. This data…
Within a primate species’ general sequence analysis there lies a potentially new open reading frame (ORF) on Line-1 5’UTR (untranslated region). This ORF is positioned in the antisense side left of the ORF1 and ORF2 already known and called ORF0. ORF0 appears in 3000+ loci…
Phytoestrogens are a group of heterogeneous herbal substances; they are called non-steroidal estrogens or estrogen-like molecules, as their structure is comparable to 17-β-estradiol structure, phytoestrogens are diphonelic compounds however they are non-steroidal substance despite their structural resemblance with estradiol, Presently phytoestrogens group contains more than…
The Human Immunodeficiency Virus (HIV) has affected millions of people worldwide, more especially in sub-Saharan Africa. The number of infections that occurred in infants in 2014 was estimated at 220, 000. Out of this, approximately ninety mine percent of the infections in infants are acquired…
The cancer stem cell (CSC) hypothesis is regarded as a reasonable explanation for the rapid multiplication of cells in the disease. They are self-sufficient cells which seem to have increase tumorigenicity and self-renewal, which allow them to expand more rapidly than normal cells. While the…
Introduction In the early years of scientific investigations in the field of heredity, the methods used to obtain data were considered genetical but once the physical basis of genetic conditions were recognized several studies were performed using methods of both cytology and genetics, using the…
Rhodiola rosea L. (R. rosea) is an adaptogenic plant that increases body’s resistance to stress. Studies have provided evidence of R. rosea efficacy mainly in models of chronic stress; only scarce data exist on its effect in acute stress and the underlying mechanisms. The objective…
The BBC article “Gene editing wipes out mosquitoes in the lab” discusses work using a gene editing technique to suppress populations of caged mosquitoes Anopheles gambiae, which transmits malaria. In 2016 were 216 million cases of malaria in 91 countries and 445000 people were killed…
Will humans be able to edit our genes to be able to decrease the risk of certain genetic defects being passed down through generations, or be able to give same-sex couples the opportunity to have their own genetic children? Genetic editing has been the basis…
Who would’ve thought that scientists were wrong, that the “negro-race” would still be here today. At the turn of the 20th century, Social Darwinists looked censuses to predict the extinction of the Negro race. It was hypothesized that the Negro would eventually become extinct by…
Cancer The basics of cancer In your body cells are constantly being reproduced for different reasons. Sometimes your body gets out of order and produces cells. Which if they aren’t corrected quickly this how cancer forms. Cancer can form in any part of the body…
The word clone is used in many different contexts in biology research, however, it all comes down to the simplest form, it refers to a precise “genetic copy of a molecule, cell, plant, animal, or human being” (Sunstein,1999). For cloning to take off, there were…
