James Schlatter, a research chemist working to develop an anti-ulcer drug, inadvertently got some of the substance on his fingers. When he later licked his fingers to pick up a piece, his fingers tasted very sweet, and he correctly linked the sweetness back to the anti-ulcer drug. Instead of finding an anti-ulcer drug, he discovered aspartame (NutraSweet), now the dominant commercial artificial sweetener. Purpose:

In eukaryotes, genetic information is passed to the next generation by processes that include mitosis or meiosis. which of the explanations identifies the correct process and supports the claim that heritable information is passed from one generation to another? a. mitosis, followed by cytokinesis, produces daughter cells that are genetically different from the parent cell, thus insuring variation within the population. b. during mitosis, dna replication occurs twice within the cell cycle to insure a full set of chromosomes within each of the daughter cells produced. c. in asexual reproduction, a single individual is the sole parent and passes copies of its genes to its offspring without the fusion of gametes. d. single-celled organisms can fuse their cells, reproducing asexually through mitosis to form new cells that are not identical to the parent cell.
