Answer:
At least 17 PCR cycles or 16 PCR cycles
Explanation:
As we know -
In one chain of heating and cooling of polymerase chain reaction (PCR), the strands of DNA gets doubled.
The general mathematical representation of this is
where "n" is the number of PCR cycles.
It is given that DNA strands to be produced is 16 times the original quantity of DNA.
So the PCR cycle must be carried out at least 17 times in order to have DNA strand not less than 16 times the original quantity of DNA
Answer:
The correct option is b. DNA ligase
Explanation:
DNA ligase is an enzyme that joins DNA fragments. If two DNA fragments or molecules have complementary ends, the ligase can join them together to form a single and intact DNA molecule, without interruptions. This is because the ligase enzyme seals the space between the molecules to form a single DNA fragment.
The others enzymes have different functions:
DNA helicase is characterized by separating DNA from double strands into single strands and acts in DNA replication.
ATP methylase plays an important role in DNA replication when determining the beginning of replication that has already been replicated or not.
DNA polymerase is an enzyme that is responsible for catalyzing the polymerization of the new strand of DNA during the replication of this molecule.
Do you know what a pangea is well Pangea is another supercontinent the reason why we're not Pangea is because something dead which oceans with lava cools off it cools off from old to new the new rocks are pushing the consonants together and eventually and a couple of million years it will be Pangaea again
Answer:
tropical forests can be found in this region.
Las Ciencias de la Tierra o Geociencias conciernen y engloban las disciplinas que estudian la estructura, morfología, evolución, y dinámica del planeta Tierra. Constituye un caso particular de las ciencias planetarias, que se ocupan ellas del estudio de los planetas del Sistema Solar.
