Genetics and Chromosomal Concepts

This video tutorial is the third activity in the IB Biology course, focusing on the use of databases in genetics. It guides students through using the OMIM database to identify the locus of human genes and their polypeptide products. The activity involves searching for specific genes, understanding their functions, and locating them on chromosomes. The tutorial provides a practical example using the DRD4 gene and explores searching genes on specific chromosomes, such as the X chromosome. The video concludes with contact information for further engagement.
