How can there be 64 codon combinations but only 20 possible amino acids?

The amino acids in a colon can be in multiple different orders, even those there’s twenty amino acids they can be rearranged and different amino acids can be in combination in a codon, hope this helps!

Theo Rich

ProOnline lessons

Enthusiastic and friendly tutor in Biology, Chemistry, Maths, Chinese, and 11+ / ISEB exams.

Hi there! My name is Theo and I am a Year 13 student studying Biology, Chemistry, Maths, and Chinese (4 A*s, 11 GCSE Grade 9s), looking to pursue medicine at university. I am particularly fascinated by human biology and biochemistry, but enjoy learning about other subjects that interest me, such as politics and Chinese history and culture. I thoroughly enjoy teaching, and would love to take the opportunity to share my academic knowledge and other insights as a mentor. For the last year I have worked for two hours a week as a voluntary tutor, where I have developed the skills and understanding required to be a successful tutor. I also find it incredibly exciting and rewarding to see students develop and get to grips with new topics, as well as be enthusiastic about topics I'm also keen on! I enjoy a student-led approach to tutoring, where the goals and targets of the student are our primary focus, such as an upcoming exam. What I quite like to do is, if there is a particular topic that the student would like to focus on, then we can go through the theory of it together, but if not, it can be really beneficial to go through past paper questions together and then pause and reflect on any topics that are particularly challenging.

A tutor that understands you

Hi, I'm Rachel! I am currently studying Biology as an undergraduate at University College London and have gained a lot of experience tutoring in the subject over the past couple of years. I love the depth and breadth that Biology offers and I would love to share my passion for the subject with others. I believe in tailoring my education to each individual student, as everyone learns slightly differently so it makes sense to have a lesson that is specifically designed for them. I take time in planning my lessons and work with each student to find the harder topics that need a bit more attention. I am more than happy to answer any questions you have!

I'm a curious and ambitious medical student and teacher!

Hi everyone, My name is Carola and I am originally from Italy. Travelling has always been a passion, and after an exchange programme in Vancouver (Canada) I decided to move to London. I recently graduates with a 1st in Biomedical Science from QMUL and I will start Medicine at Barts this September. I have been tutouring all levels (from elementary school to adult learner) in a variety of subjects. I am an ambitious and curious student, so be sure that if I don't know how to answer one of your questions, I will make sure to do some reseacher and let you know as soon as possible!
