Degree: Biological Sciences with Hons Molecular Genetics (Bachelors) - Edinburgh University
I am in my final year studying towards a degree in Molecular Genetics at the University of Edinburgh. Whilst my expertise is in cell biology and genetics I've also studied a broad range of biological subjects during my 8 years of Biology education (eg. evolutionary biology, biomedical sciences, biotechnology...). My special interest is in the myriad of way cells regulate gene expression.
It continually amazes me to learn about what is going on at a microscopic (and below!) level in my own body, and learning about how other organisms have come to completely different solutions to the same biological problems! One of the things I love about biology is that it is so uncertain and messy - things that might seem straightforward are often not that simple. I believe this is what makes the subject so fun to learn about and also accessible - the kind of questions you come up with as you learn new material are probably the same questions scientists are trying to answer!
Having worked in two laboratories I can use my practical experience to help explain the experimental side of your course as there is a great deal of focus on 'how we know what we know'. I can also provide advice for those of you considering careers in science, as I feel like from my own experience of school the only biology career I knew about was medicine!
When I was studying at GCSE and A level I found that sometimes material is presented with little context and that makes it hard to remember. What I hope to provide is a broader context rich with stories and examples that will make the bare facts stick in your mind a little more.
In biology, like other sciences, an understanding of the basics will take you a long way in understanding more complex subject matter. I will explain anything you like in a variety of ways, with diagrams, analogies etc. until you are able to explain it back to me. It's important to me to foster a relationship with my tutees where you can ask any question at all and get a satisfying answer (or at least have a good discussion about it!) You will probably be surprised by how much is still unknown!
Obviously, the focus here is on preparing students for their examinations and I will follow the syllabus closely. My first goal is to foster basic understanding of concepts, secondly I feel the best way to study is by trying to solve problems and answer exam questions together. I also believe that by offering a little bit of extra context and having discussions with students about current thinking in the field, how scientists come to the conclusions that textbooks are written about! etc. I can inspire the enthusiasm that really motivates students to succeed.
If you have any questions, send me a 'WebMail' or book a 'Meet the Tutor Session'! (both accessible through this website). Remember to tell me your exam board and what you're struggling with.
I look forward to chatting with you!

There are three main differences between DNA and RNA:
1. RNA has the base uracil instead of the base thymine. These bases are very similar and differ by only one chemical group!
2. RNA nucleotides have a ribose sugar instead of a deoxyribose sugar like DNA. Having an extra OH groups mean that RNA nucleotides are more likely to suffer nucleophilic attacks. This is one of the reasons RNA is more unstable than DNA.
3. Usually in the cell DNA forms a double stranded helix, whereas RNA is usually single stranded. Cells make all kinds of weird and wonderful RNA molecules, some of these do have secondary structures and regions of double strandedness. For GCSE you learn about tRNA for example, this RNA folds back on itself and so has double stranded regions.see more
