Since this time, research has focused on biological factors that may lead to autistic behaviours. This has found very clearly there is no one cause of autism. A variety of genetic factors are likely to be the ultimate cause of most cases of autism. These may work by themselves, or in combination with environmental factors, to lead a child's brain to develop differently and result in autistic behaviours.

Four talks focus on sex determination-the molecular and genetic mechanisms that determine whether an organism will be male, female or a hermaphrodite.

 This session will showcase several PBL lessons and units that incorporate multiple Common Instructional Framework Strategies and authentic inquiry experiences in order to facilitate mastery of science concepts.

This web site provides tools and resources that support ambitious science instruction at the middle school and high school levels. Ambitious teaching deliberately aims to get students of all racial, ethnic, and class backgrounds to understand science ideas, participate in the discourses of the discipline, and solve authentic problems. We describe 4 core instructional strategies that support this kind of teaching. These "high-leverage" practices make up the Science Learning Framework (below), and have been selected based on extensive research of how young people learn science, on authentic forms of science activity, and how teachers learn to appropriate new practices.

DNA to Darwin allows 16-19 year-old school students to explore the molecular evidence for evolution through practical bioinformatics activities that use data analysis tools and molecular data. Each of the activities on this web site centres around an engaging story from recent research in molecular genetics encompassing microbiology, plant and animal biology and human evolution.

5:12 video animation describes the basics of enzyme structure and function. This includes enzyme substrates and active sites, enzyme denaturation, and competitive and non-competitive inhibition.

Hereditary methemoglobinemia (met-H) is a human genetic disease that is inherited as an autosomal recessive.
