December 14, 2012
Dr. Jason Tresser explains how genes can be compared between members of the same species or between similar species. This process can be used to track where genes have changed over time, and can be...
December 12, 2012
Dr. Jason Tresser describes how alleles can be tracked in a population. He explains the Hardy-Weinberg Law, which outlines the conditions for genetic stasis, and the ways genes are commonly seen to...
December 10, 2012
Dr. Jason Tresser explains the origin and behavior of cancer cells. He describes the various ways that these cells can be identified and some of the ways that they can be treated.
December 7, 2012
Dr. Jason Tresser explains the developmental processes of embryos as they differentiate into various types of cells. He explains the general mechanisms that surround this process and how the proces...
December 5, 2012
Dr. Jason Tresser discusses with his class the ethical issues raised by embryonic research. He argues for the sanctity of life and presents several unique alternatives to the commonly presented opt...
November 30, 2012
Dr. Jason Tresser explains how gene expression is regulated in a cell beyond the DNA phase. He explains how various types of RNA can interact with and edit one another, as well as how a protein can...
November 28, 2012
Dr. Jason Tresser explains how the expression of genes is controlled in multicellular organisms. He describes the various types of proteins that act as activators and repressors in a cell.
November 26, 2012
Dr. Jason Tresser explains the controlling factors of gene expression in a bacterial cell. He describes the regions of genetic code that activate or repress a gene and how these function in respons...
November 19, 2012
Dr. Jason Tresser explains how transgenics can be used to identity the expression of particular genes in an organism. He describes how genes can be probed to identify the mRNA being expressed in a ...
November 14, 2012
Dr. Jason Tresser concludes his teaching on genotyping and goes on to discuss transgenics. He explains the necessary components of a gene that must be in place for a host cell to utilize a foreign ...
October 24, 2012
Dr. Jason Tresser explains the various types of mutations that can occur in an organism's genetic material. He explains how mutations can be chemically induced as well as how they can appear natura...
September 28, 2012
Dr. Jason Tresser teaches Mendel's laws of genetics and how these can be used to predict the phenotypes of offspring. He then goes on to explain how these manifest during meiosis and the process of...
September 7, 2012
Dr. Jason Tresser explains the structure of DNA and RNA. He goes on to discuss how genomes are stored within cells and the structures used to condense DNA to a manageable size.
