UNIT 6 DNA, RNA, Replication and Protein Synthesis
Essential ideas
The structure of DNA is ideally suited to its function.
The structure of DNA allows efficient storage of genetic information.
Information stored as a code in DNA is copied onto mRNA.
Genetic information in DNA can be accurately copied and can be translated to make the proteins needed by the cell.

DNA Replication Workbook activity 56-57 |
Watch this intro video first:Watch this short video about complementary base pairing:Now complete the following activity on this site:12. Semi conservative replication.ppt 12b. DNA Replication worksheet Use the Kognity section to review the Meselson and Stahl evidence for DNA replication.You will now research and compile a poster to present the additional HL material for DNA replication: 13. DNA replication AHL Use this QUIZLET to practice You will then complete the DNA Replication challenge |

DNA Replication (About 10 minutes) |
Transcription Workbook activity 58-60 |
An overview of protein synthesis: 13. Protein synthesis overview You may use this presentation to recap your prior knowledge and move into the HL material As we are Online Learning we will be using some alternative learning resources to help build your understanding. Go to Learn Genetics to begin with an interactive exploration into how a gene is transcribed and translated into a protein. Work through the exploration whilst making your own notes with diagrams. You may repeat this for a different gene in the nucleus to test your understanding. Now you are going to watch a video about how a firefly's tail makes light

Review |
Recap using Kognity for sections for 2.6, 2.7, 7.2 and 7.3 Read through each section, complete the section check points, complete the practice questions and written answer questions. |
Don't be disheartened - this IS difficult stuff! Be sure to try all the support material and additional activities I have included. Scale it back to the basics and then build up your understanding slowly. |
