Study Like a Boss
Charles Darwin and Jean-Baptiste Lamarck had a scientific debate about the process of evolution. Darwin’s theory of evolution is by natural selection. Organisms change over time as a result of heritable physical and behavioural trait changes. The changes were due to the genes in the gene pool due to environmental pressures. For example: skull shape, … Read more
The benefit verses the effect of fetal Magnetic Resonance Imaging has been a controversial subject for years. Magnetic Resonance Imaging is a helpful tool for diagnosis of many diseases and abnormalities, but is it actually harmful to the fetus? Do the benefits of the Magnetic Resonance Imaging outweigh the risks? Ultrasound is the mostly commonly … Read more
There are many current legal and ethical issues in bioengineering and biotechnology including athletic and cognitive enhancements, stem cell research, cloning, genetic engineering, and genetically modified organisms. Biotechnology is “the manipulation of biological systems and organisms through technological means”(p. 471). There is tension between valuing liberty to pursue happiness of biotechnologies, and the potential negative … Read more
Though out many years, movies and television shows such as Star Wars, Star Trek, and many others have enlightened our imagination on cloning organisms. Today, it appears that this idea that looked unreachable, now seems to be within our grasp due to our technological leap in genomic science. But we are not interested in just … Read more
In this essay I will discuss the adaptations on human evolution, this includes skin color, disease, Lactase Persistence, and the negative effects of the Neolithic Revolution. I will focus mostly on the diseased portion the most because this plays a vital role in natural selection. Natural selection is the process whereby organisms better adapted to … Read more
Imagine a world where we can have two of everything. Think about the possibilities. Imagine having two Ankits. Actually, I kinda want to take that back now. One Ankit is already too much. I might as well walk myself off the stage, but before that happens, I need to tell you a bit about genetic … Read more

Inside of every single cell in … Read more
In research facilities all around the world scientist are attempting to stop diseases at their very roots. Instead of trying to find drugs to cure illnesses they are trying to change the genes that cause the diseases. The process by which this is done is called gene therapy. Gene therapy is the deliberate alteration of … Read more
The engineering of deoxyribonucleic acid (DNA) is entirely new, yet genetics, as a field of science, has fascinated mankind for over 2,000 years.

It all started back in the fifties when James Watson and Francis Crick discovered the structure of DNA (DSouza NA). Ever since there has been talk of human and animal cloning. It all seemed out of reach and basically impossible, but in 1997 that all changed when a sheep, named Dolly, was the first ever … Read more
Scientists are taking medical technology to new heights as they race to map all of the genes in our body. There are about 100,000, in the 23 chromosomes of the human body. In doing this they hope that they can understand the basis of the genes and maybe even develop methods of treating certain genetic … Read more
Genetic engineering is the alteration of an organism’s DNA, or genetic, material to eliminate undesirable characteristics or to produce desirable new ones. The most controversial form of genetic engineering, by far, is cloning. Cloning is another technology that has evolved out of genetic research. While genetic engineering usually adds or removes just one or two … Read more

Genes, or chromosomes, are often referred to as “blueprints” which are passed down from generation to generation. From the study of these hereditary materials, scientists have ventured into the recent, and rather controversial, field of genetic engineering. It is described as the “artificial modification of the genetic code of a living organism”, and involves the … Read more
In the human body, each cell contains 23 pairs of chromosomes, one of each pair inherited through the egg from the mother, and the other inherited through the sperm of the father. Of these chromosomes, those that determine sex are X and Y. Females have XX and males have XY. In addition to the information … Read more
