Many believe that DNA is the silver bullet in a crime scene investigation, to which I strongly disagree. Quoting Chris Alpen, ‘DNA can never replace a thoughtful, creative detective with the right resources’, and that ‘technology is ultimately a system run by humans where mistakes can and will be made, regardless of how advanced it is.’ DNA is powerful in...

Phrenology was a pseudoscience that aimed to study the size and shapes of skulls in order to determine one’s mental abilities, or lack thereof (Real Archaeology, 2017). This “science” was welcomed in the early 1800’s but it has since been refused by most scientists for at least the past 50 or 60 years. Even though we may reject it now,...

Life is a DNA driven programme and death results from its technical failure. Protein and DNA were evolved naturally from the gas present in the environment of the primitive world. It was the effect of high voltage thunderbolts and asteroid hits on the surface of the earth. Millions of years ago passage of the high voltage energy across the environmental...

First recognized in 1926, ataxia-telangiectasia, otherwise referred to as AT, is an extremely rare and ineluctably progressive disease which slowly denigrates the nervous system. Ataxia–telangiectasia is an autosomal recessive, caused by mutations in the ataxia–telangiectasia mutated gene (ATM), which is best described as a serine/threonine kinase that activates over two dozen proteins involved in controlling cell growth and division. Individuals...

Abstract An important method used in biology is plasmid purification. What makes this method so important is because a purified plasmid sample is essential for many experiments, including important techniques like DNA sequencing. Purified E.coli plasmid pBR322 using gel electrophoresis and a calibration curve were used in this experiment to quantify the size of the purified plasmid. Examples were examined...

The reuptake of dopamine within the brain is initiated by proteins referred to as “Dopamine Transporters” (DAT) found in-between neurons. DAT act on the pre-synaptic neurons nerve endings and allows them to absorb the dopamine neurotransmitter, thus terminating the transmission of a message. The reuptake and regulation of dopamine results in a steady and level headed mental state. Dopamine as...

A gene is a nucleotide sequence which dictates the synthesis of a particular RNA or protein molecule. Their control over the produced proteins govern both phenotypical and genetic traits, including susceptibility to diseases like Cystic Fibrosis. Driving gene expression is Central Dogma, a two-step process in which DNA is converted to an intermediate RNA (mRNA) through transcription, then from mRNA...

Gene Therapy consists of modifying the genes within somatic cells to treat or prevent a disease. The reason this is possible is because genes contain our DNA, which is what decides a huge part of a person and what they look like. When a gene is damaged or missing, it can lead to health issues making gene therapy an option...

In 1940, biologist had a hard time accepting DNA as genetic information due to its chemistry (The Structure and Function of DNA, n.d.). DNA is a nucleic acid and is where genetic information is stored in a molecule to build and maintain an organism (DNA structure and function, 2014). DNA is known as the molecule of heredity (Gaughan, 2019). The...
