About me
Hi, I am Georgie and I am starting a Biology Masters at The University of York in September. I am very passionate about science and I want to go into teaching in the future. I am very friendly and bubbly so I hope that I can pass on my enthusiasm for science, and inspire you to explore science at University!
My exams were not that long ago and I remember being very nervous for them, as I was very under-confident in my abilities and knowledge. I understand that they are the most stressful years at school but I hope I can provide reassurance that you do survive! I hope to use this experience as extra drive to ensure that you get the grades that you deserve to allow to get where you want to be.
I have worked with My Tutor for over two years and have tutored a range of students from GCSE to A-Level. I have tutored students throughout the academic year who have achieved very good exam results, as well as one-off sessions to help clarify certain topics.
About my sessions
I enjoy finding creative ways to teach new ideas that are specific to your learning style. I want you to come away from a session feeling comfortable with the topics discussed. I believe that past papers are the best way to learn how to do well in the exam and I will focus on the specific phrases that examiners want. Most importantly I want you to have fun and come away from the tutorials with less stress and more confidence.

Questions Georgina has answered
How does information from a gene make a protein?
A gene is defined as a section of DNA that codes for a protein. Within a gene you have triplets which are 3 bases in a row that code for a specific amino acid. However there might be many triplet codes per amino acid. Amino acids are the building blocks of proteins so the cell transfers the information in the gene into a protein in two major steps: Transcription and Translation. Below the steps are explained as if in a eukaryotic cell.
1. Transcription - DNA to mRNA
Initially helicase unzips the DNA helix by breaking the double bonds. This exposes the bases of the sense strand of DNA, which is used to make a complementary mRNA strand. RNA polymerase joins the RNA nucleotides to form a single strand of mRNA which leaves the nucleus through a pore in the nuclear envelope. The triplet codes in the DNA are now called codons within the mRNA strand. The base T (thymine) has also been exchanged for U (uracil).
2. Translation - mRNA to protein
This step occurs within ribosomes which are located either free in the cell or on the rough endoplasmic reticulum. The amino acids are carried by tRNA which has 3 bases which code for a specific anti-codon to the amino acid being carried. This anti-codon will be complentary to a specific codon in mRNA which is the mRNA form of the triplet coded in the DNA at the beginning.
The mRNA from the nucleus moves into the ribosome and the first codon is called a start codon which initiates translation. tRNA molecules then bind to each specific codon in order and the amino acids carried are bonded together via a peptide bond. The empty tRNA molecule then leaves the ribosome. This process continues until the ribosome reaches the end of the mRNA strand and stops at the stop codon which does not code for an amino acid. The polypeptide chain is then released and it folds into its secondary structure. The protein is most likely to then move to the golgi apparatus where it is edited and modified into its final structure.
