  1. bind a transition state intermediate, such that it cannot be converted back to substrate.

  2. ensure that all of the substrate is converted to product.

  3. ensure that the product is more stable than the substrate.

  4. increase the rate at which substrate is converted into product.

#8. Inheritance Biology

In the pearl-millet plant, color is determined by three alleles at a single locus: Rp1 (red), Rp2 (purple), and rp (green). Red is dominant over purple and green, and purple is dominant over green (Rp1 > Rp2 > rp). What will be expected phenotypes and ratios of offspring produced by the Rp1/rp × Rp2/rp crosses?
