Saccharomyces cerevisiae (a yeast species) mutants are available that grow on pyruvate or ethanol, but not sugars or glycerol.
mezya [45]

Answer:

The enzyme is the pyruvate kinase

Explanation:

The designated enzyme can only grow in pyruvate or in ethanol. They are said to be in anaerobic conditions. If the end product of glycolysis is pyruvate and the enzyme that transforms phosphoenol pyruvate into pyruvate is called pyruvate kinase. In a reaction under anaerobic conditions, the pyruvate is transformed into ethanol. So if the pyruvate kinase enzyme is mutated, pyruvate cannot be transformed into ethanol and Saccharomyces cerevisiae could not survive in that medium.

  • Meiosis, then again, is a particular type of cell division that happens in living beings that imitate explicitly. As referenced above, it produces regenerative cells, for example, sperm cells, egg cells, and spores in plants and parasites.  
  • In people, extraordinary cells called germ cells experience meiosis and at last offer ascent to sperm or eggs. Germ cells contain a total arrangement of 46 chromosomes (23 maternal chromosomes and 23 fatherly chromosomes). Before the finish of meiosis, the subsequent regenerative cells, or gametes, each have 23 hereditarily one of a kind chromosomes.
  • Hence, the right answer is option C "four strings, each a combination of different colors"
