Answer:
The correct answer is c.With an RNA virus, radioactive RNA would have been in the final pellet.
Explanation:
Hershey and Chase infected<em> E.coil</em> with bacteriophage which was having DNA as its genetic material. The bacteriophage was labeled with radioactive sulfur and radioactive phosphorus and it was radioactive phosphorus that was found in the bacterial cells or pellet.
As because DNA contains phosphorus, not protein therefore they it was proved that DNA is the genetic material. Similarly, RNA is also a nucleic acid which is genetic material for many viruses and contains phosphorus.
So if Hershey and chase might have chosen an RNA virus then radioactive RNA would have been present in the pellet. So the correct answer is c.
Answer: is accomplished by DNA polymerase.
Explanation: DNA polymerase is an enzyme that catalyzes the synthesis of a complementary strand of a DNA molecule during replication. The double stranded DNA helix is first unwind by the enzyme known as helicase giving rise to two DNA strands which serve as templates for replication. DNA polymerase then binds to a primer, a short nucleotide sequence and catalyzes the attachment of nucleotides to the primer to form a growing strand that is complementary to the parent DNA.
I think it might be metaphase because all of the chromosomes are lined up in the middle :) either that or anaphase!
Answer:
difference in density
Explanation:
We know that the high central density suggests the earth must be rich in nickel and iron and that much of the core must be liquid. This lower-density air then rises and is replaced by cooler, higher-density air. The result is atmospheric circulation that drives the weather and climate through redistribution of thermal energy.
