DNA is called the "ladder of life," and rightly so. Every living organism on planet Earth has DNA as its hereditary molecule. What's more, the code that DNA contains, in which every three bases is the code for a specific amino acid, is the...

Polymerase chain reaction (PCR) is a revolutionary molecular biology technique that is currently used in a wide array of medical and biological laboratories for a variety of applications. Introduced in 1983 by Kary Mullis, it is a technique that employs the basic machinery of cellular...

Embrionic Stem cell research is something that is currently and has for a while caused a lot of controversy. Many religious people believe that it is wrong to interfere with nature and by using these stem cells which are taken from a human fertilised egg...

Mitosis is the process by which one cell divides and becomes two. During mitosis, a chemical reaction called transcription disrupts the meta stable hydrogen bonds that hold the two single strands of the DNA molecule in its helical embrace. This transcription process is promoted by...

For most organisms on this planet the purpose of this life is to pass on genetic material, to be used like a manual by its offspring, in order to create the next generation of its species. Genetic material is information, and each of these blue-...

This article will tackle the ethical arguments against the use of hybrid or "chimera" embryos involving mixing animal and human DNA. It will try to analyse and criticise these arguments with the aim of justifying it mainly from a utilitarian perspective but also to warn...

Stem cells are normally harvested from embryos but over recent years, medical breakthrough has allowed the discovery of stem cells from organs and tissues in adults. As a result, there has been an increase in tremendous support for adult stem cell technology due to reasons...

DNA transcription is a method used by our cells to create templates from our naked DNA called mRNA, which is then translated into proteins to be used in our bodies. Different proteins are coded for by different genes, these genes are regulated through upstream cis-acting...

A mutation is the change in the genetic code whether it be through the DNA or the RNA. In essence, the many base pairs continue to appear and appear over the chain and from time to time, there is an error. However, what exactly is...

Gene expression is defined as the transcription of a gene's DNA to messenger RNA, or mRNA, which is in turn translated into amino acids, the building blocks of proteins. Proteins are responsible for the millions of molecular reactions that take place in the cells of...
