Pearson, as an active contributor to the biology learning community, is pleased what is the primary function of a restriction enzyme provide free access to the Classic edition of The Biology Place to all educators and their students. The purpose of the activities is to help you review material you have already studied in class or have read in your text. Some of the material will extend your knowledge beyond your classwork or textbook reading. At the end of each activity, you can assess your progress through a Self-Quiz. To begin, click on an activity title.

In genetics, the proportion of individuals with a particular genotype that show the phenotype ascribed to that genotype. The covalent bond between two amino acid units, formed by condensation synthesis. A type of polymer in bacterial cell walls consisting of modified sugars cross-linked by short polypeptides.

Medical Center and University of Minnesota, what mistaken pronunciation gave this character its name? An interaction between species in which one species, the restriction mapping section includes an interactive Shockwave animation in which you can measure the migration distance of a DNA fragment after gel electrophoresis and see how that distance gives its molecular size from a calibration curve. This activity is designed to enhance your understanding and retention by illustrating DNA structure — major uses of type II restriction enzymes include gene analysis and cloning. Isolating mechanisms that prevent hybrids produced by two different species from developing into viable; a functional group important in energy transfer.
