RNAse is an enzyme that cleaves the P–O^5′ bond in RNA. it has two His residues in the active site. Suggest a plausible explanation why the enzyme activity changes when pH is increased or decreased from ~pH 6.0, Choose all the true statements a.) the RNAse reaction is an example […]

1) Determine where are the hydrophobic or hydrophilic residues concentrated? Where does your mutation fall relative to these clusters and to the inside/outside of the protein? 2)What (if any) are the primary partner(s) or binding site component(s) [such as a heme, DNA, GSH (Glutathione)? It should be obvious to you […]

Shown here are the amino acid sequences of the wild-type and three mutant forms of a short protein. Use this information to answer the following questions: Wild type: mer-trp-tyr-arg-gly-ser-pro-thrMutant 1: met-trpMutant 2: met-trp-his-arg-gly-ser-pro-thrMutant 3: met-cys-ile-val-val-val-gln-his Using Figure 13-7, predict the type of mutation that occurred leading to each altered protein.For […]

Biodiversity is the variety of species living in the world.  Biodiversity is important for the survival of species because we are all part of something much greater than ourselves.  We need a variety of species to provide us with our food supply.  Each species have to depend on another species […]
