History of DNA Models
Up until James Watson and Francis Crick's experiments, we had very little understanding of exactly what made living things look and appear as they do. Other models had been proposed,…
DNA Strand Diagram
The below mentioned article provides a diagram of DNA strand. (a) DNA is made up of two polynucleotide chains. The backbone is constituted by sugar-phosphate, while the nitrogenous bases project…
Secondary Structure of DNA and RNA
Secondary Structure of Deoxyribonucleic Acids: Some observations made on deoxyribonucleic acids in solution suggested that DNA molecules — as they could be extracted from cells — had structural characteristics different…
What is a Phosphodiester bond?
A phospodiester bond is a covalent bond in which a phosphate group joins adjacent carbons through ester linkages. The bond is the result of a condensation reaction between a hydroxyl…
DNA and RNA structure: nucleic acids as genetic material
Last month, we covered the definition of molecular diagnostics (MDx) as the detection of nucleic acids to provide clinical information. The methods used to do so, as well as the…
Creating a Secure REST API in Node.js
Consider all the software that you use in your life. It doesn’t matter if you’re a developer or a regular user that just casually browses the internet and checks up…
Nucleic acid
Nucleic acid, naturally occurring chemical compound that is capable of being broken down to yield phosphoric acid, sugars, and a mixture of organic bases (purines and pyrimidines). Nucleic acids are the main information-carrying…
BIOREMEDIATION: THE POLLUTION SOLUTION?
The global population continues to rise at an astonishing rate, with estimates suggesting it will be in excess of 9 billion in 2050. The intensive agricultural and industrial systems needed…
Bioremediation: What Is It and What Does It Do?
What is Bioremediation? Bioremediation, in simple terms, is the use of microorganisms to degrade contaminants that pose environmental and human risks. The concept and use of bioremediation come from the…
