Biofuels, Natural Gas, Wave Energy, etc.
Explanation:
what is it? Alternative energy sources is any energy sources that is alternative to fossil fuels
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).
When there isn't enough room in the cell for two complete molecules of DNA, the prokaryote stops replication and undergoes cell division.
