Current State of Developmental Biology

Developmental Biology is an exciting and dynamic field. The classical methods of isolating and transplantating embryonic parts have been complemented by modern techniques including genetic analysis, advanced microscopy, as well as DNA cloning and sequencing. Accordingly, this course offers a blend of classical and modern topics, which are organized in three parts (see Syllabus and Textbook).

In a fast-moving field like developmental biology, it is inevitable that textbooks become dated during the intervals between revisions. This web site therefore contains extensive files with Answers, Comments, and Updates for each textbook chapter.


Major Goals of this Course

In accord with these goals, the course is organized by phenomena and concepts, not by animal groups or organ systems. Examples are picked as they serve best to illustrate the general points to be made. Mammals or other vertebrates will be preferred whenever possible because we have a natural interest in their development. However, many important investigations have used invertebrates because they lend themselves better to experimentation and genetic analysis.



The prerequisites for this course is BIO 325 with a grade of at least C.

Previous upper division course work in molecular biology and/or cell biology will facilitate taking this course but is not required. The textbook used in BIO 349 has a remedial chapter on relevant topics in cell biology, and several chapters contain methods boxes that explain required terms and techniques in molecular biology. Also, textbooks on Molecular Cell Biology will be held on reserve for students in this class.
