Question

3. The fact that the genetic code is universal suggests that:

A. All organisms evolved from separate original ancestors.
B. Life forms have a common evolutionary ancestry.
C. Protein makes up the genetic material.
D. Evolution does not really occur.

Answer 1

B. Life forms have a common evolutionary ancestry.

Step-by-step explanation:

A. All organisms evolved from separate original ancestors.

-> We know this is not true. If organisms evolved from separate ancestors, they would have different genetic code.

C. Protein makes up the genetic material.

-> This was proven false in Hershey–Chase experiment.

D. Evolution does not really occur.

->This one's obviously false as speciation happens regularly.
