  • What is Protein Docking?

    Macromolecular docking describes the way in which two very large molecules approach and interact with each other—in effect joining themselves—at least temporarily. Of prime importance in this maneuver is so-called "quaternary structure...

  • Protein Interactions – Interactions Between Proteins and Molecules

    Proteins interact with other macromolecules, including other proteins. Among such interactions is replication. Protein interactions at cellular walls engaging other molecules must be limited, transient—allowing disengagement upon task completion...

  • Life Cycle of Plants: Alternation of Generations

    The life cycle of plants includes alternation of generations, where two generations complete a life cycle. A haploid gametophyte form alternates with a diploid sporophyte form.

  • Gene Therapy for Cancer

    An effective gene therapy cure for cancer would be a major step forward in medical technology. The discovery of a gene called SARI is the cause of some optimism as it suppresses a key protein that is over expressed in most cancers.

  • The Genetic Code

    The genetic code is the translation system between the nucleotides of DNA and RNA, and the amino acids that make up proteins.

  • Cell Division: A Comparison of Mitosis and Meiosis

    What is the difference between mitosis and meiosis? Mitosis and meiosis are two types of cell divisions. We'll discuss these differences in more detail, and also look at the phases of each.
