Chronic myeloid leukemia is a disease caused by a genetic mutation that gives rise to this abnormal protein molecule. The abnormal protein triggers the bone marrow to release dangerous numbers" of white blood cells. Gleevec, the thin...

Find out how tiny variations in DNA can help scientists predict humans' response to drugs or to disease risk.

Mutation is a process that changes a DNA sequence. But how does a difference in a gene's DNA sequence (or genotype) lead to a difference in an observable trait (or phenotype)?

See how cell division is essential for healthy growth of an organism, and how complex genetic mechanisms have evolved to switch cell division on and off at the proper time for normal development. [0:50]

Students will learn about the different types of mutations and how they work. They will compare the effect of these different types of mutations in DNA, including nucleotide substitution, nucleotide insertion, and nucleotide deletion....
