Plastic I guess is the answer
Answer:
The correct answer will be option-C.
Explanation:
DNA polymerase is an enzyme which replicates the DNA in 5' to 3' direction as well as it performs the exonuclease activity in 3' to 5'.
This exonuclease activity increases the rate of replication with high accuracy. This mechanism of proofreading is known as a proof-reading mechanism which increases the accuracy rate of DNA synthesis by 100- fold.
Thus, Option-C is the correct answer.

Meiosis is responsible for the cell division of the gametes, spermatogenesis (sperm cells) and oogenesis (egg cells), such haploid cells.
</span><span>Mitosis and meiosis are simply cell division processes that occurs differently, they're characteristically divergent from each other according to their function and structure. Mitosis is the cell division that happens in all cells in the human body except sperm and egg cells. They produce diploid cells. </span>
Answer:
This lack of fossil data is expected, because the fossil record is incomplete.
Explanation:
Fossilization is a slow, complex and extremely rare process that depends on several favorable conditions for the conservation of traces or materials left by an organism:
1 - Rapid burial of the material;
2 - Presence of rigid parts that are more resistant to degradation;
3 - The type of sediment should be thin and less prone to erosion.
4 - The environment in which the material is located should be low in oxygen to avoid degradation due to oxidation.
5 - The temperature of the place where the material is buried should preferably be cold because the action of decomposing microorganisms in these environments is much lower.
Therefore, it is very common and expected that the fossil record is incomplete.
