Genetic Testing and Chromosome Structure in Cell Division

The video explores the potential of genetic testing to predict disorders like cancer. It explains the structure and function of chromatids and chromosomes, highlighting their role during cell division. The video delves into the composition of chromosomes, revealing that they are made up of genes, which in turn consist of DNA molecules. The session concludes with a brief overview of genetic material and a segue into Mendel's laws of genetics.
