= Welcome to your wikispace on DNA and Protein Synthesis = = = = By the end of this online learning activity, you should be able to: = = = a)  Outline the relationship between genes, chromosomes, and DNA b)  Describe the structure of DNA and RNA in terms of the bases, sugar and phosphate groups found in each of their nucleotides c) Describe the similarities and differences between DNA and RNA in terms of the bases, sugar and phosphate groups found in each of their nucleotides d)  State the rule of complementary base pairing in DNA e) state that DNA is used to carry the genetic code, which is used to synthesise specific polypeptides f)  State that a gene is a sequence of nucleotides, as part of a DNA molecule, and controls the production of one polypeptide g) State that the Central Dogma of Molecular Biology as a one-way flow of information in DNA to messenger RNA and protein h)  Describe the roles of messenger RNA, transfer RNA and ribosome in the transfer of genetic information from DNA to protein i) Describe the complementary binding of codon on mRNA and anticodon on tRNA in protein synthesis

**During the course of your exploration, you might come across some very useful online resources. Please feel free to contribute & upload these links on the relevant pages.



__ Tasks: __ 1. You will be required to work in groups (of 3s or 4s) to write an essay describing DNA structure .**  1. Create a new page **__on this wikispace__**. At the top of your page, list your group members, with each name in a different colour

2. In a group, write a 300-word essay describing the **components of DNA** and **how these associate** with each other to generate the **overall, 3-dimensional structure** of DNA

3. Any member of the group can start writing the essay, with each member adding/ editing over these 3 weeks. Pls note that each member should use a different colour so everyone can track everyone else's contribution

4. At the bottom of your page/ essay, please include yopur references (again, colour coded to track contributions).


 * Deadline for Essay (online submission on wikispaces): 10th July 2359 hr.

2. You are required to complete a worksheet .

Deadline for Worksheet (hardcopy): 7th July 1330 hr.

3. At the end of your online exploration, you will be required to build a model of DNA undergoing transcription .** **(Individual work)**
 * Deadline for Model (ACE activity): 21st August 1700 hr. **
