BIOL3026: Developmental Biology

Semester 1, 2026 [Normal day] - Camperdown/Darlington, Sydney

The advent of multicellularity represents one of life's great transitions in complexity, ultimately paving the way to the evolution of complex organisms such as humans. This unit focuses on how such complex multicellular systems are constructed using both animal and plant systems in a comparative way that reveals common strategies and striking contrasts. The course will cover the multidisciplinary nature of approaches used, including classical embryology, biochemistry, genetics, transcriptomics, live-imaging, cell biology, physiology and computer simulation. Topics will include fundamental concepts, morphogens, establishing body axes, cell polarity, differentiation and commitment, evolution in the context of development, mechanics and morphogenesis with examples from model systems, stem cells and cancer. Practical work includes experiments addressing gene expression, organ identity and homeotic conversions, and uses CRISPR/Cas9 gene editing to demonstrate approaches to the study of developmental biology. The practical classes complement the theoretical aspects of the course and develops important skills in developmental biology.

Assessment summary

  • Theory exam: All students will sit a final theory exam held during the official examination period at the end of semester. The exam requires a hurdle mark of 40% to pass the Unit. The exam may comprise multiple-choice, short-answer and/or mini-essay questions from any area of the lecture and practical program. Exam assessment is compulsory and failure to attend, attempt, or submit will result in the award of an AF grade. If a second replacement exam is required, this exam may be delivered via an alternative assessment method, such as viva voce (oral exam). The alternative assessment will meet the same learning oucomes as the original exam. The format of the alternative assessment will be determined by the unit coordinator. 
  • Developmental biology presentation: Students will work in pairs to prepare a short presentation on a topic in developmental biology. Both the presentation and responses to questions will be assessed.
  • Two, small in-class multiple choice question tests. These short tests will occur during the practicals in week 4 and week 10. They will focus on lecture material.
  • Laboratory notebook assessment: Students will maintain a laboratory note book with weekly write up and final conclusions of experiments conducted throughout the semester. The laboratory note books will be submitted at various times during the semester. Several items in the note book will be selected for assessment. 

    The laboratory course is an essential part of the unit of study and students must pass the laboratory component in order to pass the unit. In order to pass students must attend 80% of practical sessions, demonstrate engagement, and submit lab notebooks for assessment (minimum of 3/4 lab notebooks). Failure to submit this material will result in AF for the Unit.

    If technical issues, illness, a requirement to isolate etc. prevent attendance at a specific class, students should discuss the problem with the coordinator to find out how to make up the missed attendance.

      Detailed information for each assessment can be found on Canvas.
