Genotypes and Phenotypes

033 - Genotypes and Phenotypes

Paul Andersen explains how changes in the genotype of an individual can affect the phenotype. He begins with genotype:phenotype::letters:story analogy. He explains how mutations can be neutral, beneficial or harmful. He also explains how mistakes in the cell cycle can lead to disorder, sterility or new species.

Madprime. Diagram of the Central Dogma, DNA to RNA to Protein, Illustrating the Genetic Code. This Happens to Be the First Few Amino Acids for the Alpha Subunit of Hemoglobin. The Sixth Amino Acid Here (glutamic Acid, "E") Is Mutated in Sickle Cell Anemia Versions of the Molecule. The mRNA Does Have a "Start Codon" Preceding This Sequence, but I Decided Not to Include It Because That Residue Is Later Removed from the Protein., May 6, 2006.
