**The preview file is a pdf version of all the slides for you to review before purchasing the real thing
This powerpoint presentation covers Topic 7.4 in the IB Biology curriculum. Specifically, it covers the details of the translation process (see learning objectives below).
Each slide is labelled with the specific learning objective and animation/video links are provided in the slide notes. The slides are formatted to print well for handouts or revision and I can provide a pdf version upon request.
As always, please let me know if you have any suggestions for improvements. These are always a work in progress!
**IB Biology Learning Objectives:
7.4.1 – Explain that each tRNA molecule is recognized by a tRNA-activating enzyme that binds a specific amino acids to the tRNA, using ATP for energy.
7.4.2 – Outline the structure of ribosomes, including protein and RNA composition, large and small subunits, three tRNA binding sites and mRNA binding sites.
7.4.3 – State that translation consists of initiation, elongation, translocation and termination.
7.4.4 – State that translation occurs in a 5’ 3’ direction.
7.4.5 – Draw and label a diagram showing the structure of a peptide bond between two amino acids.
7.4.6 – Explain the process of translation, including ribosomes, polysomes, start codons and stop codons.
7.4.7 – State that free ribosomes synthesize proteins for use primarily within the cell, and that bound ribosomes synthesize proteins primarily for secretion for lysosomes.
