The right answer for the question that is being asked and shown above is that: "b. Archaeopteryx fossils share traits with both birds and reptiles."
Answer:
This experiment proved that DNA replicated semiconservatively; half the original polynucleotide is conserved in each of the two copies
Explanation:
Semi-conservative mode of replication means that the two strands of DNA unwind from each other, and each of themacts as a template for synthesis of a new, complementary strand. As a result, two formed DNA moleculesc ontain one original strand and one new strand.
Meselson and Stahl experiment showed this model by labeling the DNA of bacteria across generations using isotopes of nitrogen ( patterns of DNA labeling showed the mode of replication).
This means that we all are the descendants of one ancestor !! thus our genes match !!
Answer:
involve calcium voltage-gated channels
