Answer:
Option A. It is produced in vitro
Explanation:
The technique of DNA vaccine involves transfer of genetically engineered or modified form of DNA into body directly with the help of injection. The DNA codes for protein, that protein is antigen and thus provides immunity.
The DNA vaccine can be produced at a low cost and easy to purify. The DNA vaccines are produced in-vivo not in-vitro, so Option A is not a characteristic of DNA Vaccine.
The oldest oceanic crust is found at the mid-ocean ridges. Thus, option "A" is correct.
<h3>How old is the youngest oceanic crust?</h3>
The ocean crust is about younger than 200 million years (for example, smaller than 5% of the age of the earth).
The crust is most naive (still being created by volcanic eruptions) along the axis of the mid-ocean ridges and increases in age down the sides of the mid-ocean rises and out onto the more serious basin floors.
Thus, option "A" is correct.

Answer:
DNA polymerase
Explanation:
DNA polymerase enzyme catalyses the reaction of adding nucleotide to growing complementary daughter strand of DNA in the direction of 5' → 3' during elongation in the process of replication. This process requires energy which is taken from nucleotides with three phosphate groups in their backbone similar to ATP (adenine triphosphate)
DNA Replication is when DNA multiplies and make exact copies of itself as part of gene transfer.
