DNA stores genetic information, and RNA allows that information to be made use of in the cell. NUCLEOSIDES Both DNA and RNA contain nucleotides with similar components. In RNA the sugar components is ribose and deoxyribose in DNA. The prefix 'deoxy' means that an oxygen atom is missing from one of the ribose carbon atom. When a sugar bonds together with a nitrogen base, it creates a structure known as a nucleoside. There are five nitrogen bases found in RNA and DNA. These bases are divided into two categories based on their molecular structure 1. Purines (adenine & guanine) 2.
"DNA is just another operating system waiting to be hacked."
Just 60 years ago, Watson and Crick described the structure of DNA for the first time. Now, we have a map of the entire human genome, and we're making new discoveries every day. If you've been following the news about genetic markers for cancer and Alzheimer's, or the controversies surrounding stem cells and GMOs, then you've probably noticed that genetic research is rapidly changing the world. If this excites you, and you thrive on hard work and critical thinking, then studying genetics at university level might be a good fit for you.
The degree will entail plenty of lab work, and where there's lab work there are lab reports. If your writing needs a bit of support, come learn to edit your own work with Marked by Teachers' collection of biological science papers. Make the teacher-marked essays a regular study tool, and before long your writing will excel anything you've done before.
Specialising in genetics at the undergraduate level can be a starting point for careers in industry and medicine and for research in fields like genomics and conservation.
