Polynucleotides Study guides, Class notes & Summaries

What are monomers? - Monomers are *small units* which are the components of larger molecules. What are polymers? - Polymers are molecules made from *many monomers* joined together. What are examples of monomers? - *Monosaccharides, amino acids* and *nucleotides* What are examples of polymers? - *Polysaccharides, polypeptides* and *polynucleotides* What reaction allows two monomers to bond together? - A *condensation reaction* allows *two monomers* to be joined together by a chemical bond, *...

A “rogue” scientist is featured in many movies, but actual scientific discovery and advancement is done as a community, involving lots of dedicated scientists. Once a hypothesis has been supported ...

In each chapter, a set of problems tests the reader’s comprehension of the concepts in the chapter and their relation to concepts in previous chapters. Each problem set begins with some problems based on the figures in the chapter, which embody important concepts. These are followed by problems of a more general nature. WORKING WITH THE FIGURES 1. In considering Figure 1-2, if you were to extend the diagram, what would the next two stages of “magnification” beyond DNA be? Answer: Th...
