This 30-slide powerpoint presentation covers 'Topic 7.3 - Translation HL' in the 2016 IB Biology curriculum. Each slide includes the specific learning objective as well as key vocabulary that students should note.
The topic has been divided into two sections:
• A - Translation
• B - Protein Structure
The presentation itself contains minimal information as it is intended to be used with teacher guidance. There are sometimes 'Video' throughout which link to relevant and informative YouTube content. The slides are formatted to be visually pleasing and to also print well for handouts or revision. Please see the preview file (first 8 slides) for an idea of the aesthetic and level of detail in the presentation. The relevant 'Essential Knowledge' can be found below.
I have had success using these presentations to review topics after students have been exposed to the material at home. I typically have the class read relevant material (book, site, etc.) and then watch the videos the day before introducing a topic. During the class period, I use the slides to structure the discussion around the IB Bio Understandings. The remaining class time is spent reinforcing the knowledge or working on activities, written test practice, or nature of science.
**These presentations are based on the IB Biology Course Guide and do not follow any textbook
As always, please let me know if you have any suggestions for improvements. These are always a work in progress!
- U1: Initiation of translation involves assembly of the components that carry out the process.
- U2: Synthesis of the polypeptide involves a repeated cycle of events.
- U3: Disassembly of the components follows termination of translation.
- U4: Free ribosomes synthesize proteins for use primarily within the cell.
- U5: Bound ribosomes synthesize proteins primarily for secretion or for use in lysosomes.
- U6: Translation can occur immediately after transcription in prokaryotes due to the absence
of a nuclear membrane.
- U7: The sequence and number of amino acids in the polypeptide is the primary structure.
- U8: The secondary structure is the formation of alpha helices and beta pleated sheets
stabilized by hydrogen bonding.
- U9: The tertiary structure is the further folding of the polypeptide stabilized by interactions
between R groups.
- U10: The quaternary structure exists in proteins with more than one polypeptide chain.
- A1: tRNA-activating enzymes illustrate enzyme–substrate specificity and the role of phosphorylation.
- S1: Identification of polysomes in electron micrographs of prokaryotes and eukaryotes.
