DNA polymerase checks DNA for errors. DNA polymerase checks DNA for errors by breaking the hydrogen bonds between the paired nitrogen bases in the DNA molecule. This causes the molecule to separate into two individual strands.

Answer:

By proofreading activity of DNA polymerase.

Explanation:

Mutations are defined as permanent, inherited changes in the nucleotide sequence of genetic material. Mutations can be caused by errors during the DNA replication, when the enzyme DNA polymerase adds a wrong nucleotide to the growing DNA strand.

When a wrong nucleotide or base is detected (by proof-reading activity of DNA polymerase) in the growing chain, DNA replications halts and the incorrect base is removed by the enzyme's exonuclease activity. Then, DNA polymerase again starts to replicate the DNA, using its polymerizing activity.

Thus, the errors can be prevented during DNA replication by DNA polymerase as it shows both polymerizing, exonuclease and as well as proof-reading activity.

The thickest part of the crust occurs in _____.
lana [24]

Answer:

Option (3)

Explanation:

The continental crust is usually thick because it has an average thickness of about 35-40 km. In the high mountain ranges, it is the thickest, forming about 80 km on an average. These are formed when two continental plates form a sandwich pattern by sharing a convergent type of plate boundary.

For example, the thickest part of the crust is the Mt. Everest which lies in the great Himalayan range, which has started to form about 50 million years back. It is geologically the most recent mountain range.

The older mountains are continuously eroded in the geological past, as a result of which the height of the mountains is affected.

Thus, the correct answer is option (3).
