Biology 351 -Developmental Biology
Note to students: all material for this course is available on Desire2Learn
In essence, Developmental Biology is a study of cell differentiation; to its extreme extent, development of an entire organism from a single cell involves several stages of differentiation and cell interaction. The course will investigate the cellular and molecular processes involved in generating an embryo, in creating various tissues and organs, and the effect of external stimuli on development.
Upon completion of this course,students will be expected to:
* Be familiar with the genes and cellular mechanisms responsible for development.
* Understand the cellular and molecular events involved in the generation and fusion of gametes prior to and during fertilization.
* Describe the morphological changes that occur during early embryogenesis, including the events of cleavage, axis formation, gastrulation, and neurulation.
* Understand how tissue layers form and how different organs are derived from each embryonic layer.
* Understand how gene expression and cell signaling regulate developmental processes, and how cells with identical DNA content can have different developmental fates.
* Be able to identify several organisms used fo rstudying developmental processes, and describe the similarities found in the development of these very dissimilar organisms.
* Establish the relationship between developmental biology and other branches of biology such as anatomy, ecology, andevolution.
Students who take this courseshould have successfully completed Biology 142 and 142 (lecture and lab). It is recommended (but not required) that students take a 200- level laboratory course prior to taking Biology 351. Students must concurrelty enroll in the lecture and laboratory portionsof the course.
