Question

2) Yeast cells of mating type a are genetically engineered to produce only mating factor instead of the normal mating factor a. The gene for the mating factor receptor was unaltered. How will these engineered cells behave in terms of mating? A) They will only mate with normal mating type a cells. B) They will only mate with normal mating type cells. C) They will mate with each other or with normal mating type a cells, but not with normal mating type a cells. D) They will only mate each other and not with normal mating type a or a cells.

Explanation / Answer

Yeast cells of mating type a are genetically engineered to produce only mating factor alpha instead of the normal mating factor a. the gene for the mating factor receptor was unaltered therefore.
