The ABCs of DNA — Part 2
DNA Structure Nuclear DNA molecules consist of a string of ring-shaped sugar molecules attached to a phosphate backbone on one side forming the sides of the twisted-ladder-like structure and one of the four DNA bases on the other. As the name deoxyribo suggests, the ring-shaped 5-carbon sugar on nuclear DNA has lost an oxygen molecule. There are four bases* that comprise the DNA code: adenine (A), guanine (G), cytosine (C), and thymine (T). The arrangement of these four bases along the…Read More … Read entire article »

The ABCs of DNA — Part 1
DNA, short for deoxyribonucleic acid, is the blueprint for everything that makes you – you! Every living creature on Earth — and some quasi-living creatures such as viruses and prions – have a DNA blueprint telling it how and when to make which proteins. Proteins are complex polymers that constitute the basic building material of a living creature. Like a blueprint for a building, DNA uses a universal code to transmit its instructions to the ‘construction crew’ in rest of…Read More … Read entire article »
