Question

George Beadle and Edward Tatum used mutant strains of Neurospora to formulate the one-gene-one-enzyme hypothesis. Researchers later updated this hypothesis to propose that one gene encodes one polypeptide because proteins can have multiple subunits.

Consider a heterohexameric protein with all unique subunits. How many genes are required to form this protein?
a.two
b.one
c.four
d.six
e.three

Answer 1

To form a heterohexameric protein with all unique subunits, six genes are required.

Step-by-step explanation:

To form a heterohexameric protein with all unique subunits, six genes are required. Each gene encodes one polypeptide, and since there are six unique subunits in the protein, there must be six corresponding genes.
