For this particular biology project, we, the members of group 2, will be providing teaching aid in many interactive forms and quizzes that cover the topic of DNA and RNA (Chapter 8) in SBU3043 course.

Our learning aims are:
✅ Acknowledge the discovery of DNA double helix structure
✅ Illustrate the structures of DNA and RNA and compare their differences
✅ Explain the DNA replication process
✅ Discuss the processes of transcription and translation that involved in gene expression

Learning scope or subtopics that we are going to cover are:
🧬 History: Discovery of DNA 
🧬 DNA: Structure and Function & The Differences of DNA and RNA
🧬 DNA Replication
🧬 RNA: Structure and Function & Different Types of RNA
🧬 Gene Expression: Transcription and Translation

We would also like to introduce ourselves! Meet our team:
💠 Nurul Izzah Iliyani binti Mohd Ramli (D20211100743)

💠 Nur Ashyima binti Abdul Asis (D20201093793)
💠 Nur Hazimah binti Harifudin (D20201095489)

We sincerely hope our teaching aid could assist the students to revise important concepts of DNA and RNA by illustrating their structural differences, describing their functions and elaborating all processes involved such as DNA replication and gene expression in living organisms, specifically in eukaryotes cells. 

Feel free to leave your feedback in order for us to improvise our teaching aid in the future. Happy reading and happy learning! 📚
