Answer:
The tundra biome
Explanation:
The permafrost are defined as the thick subsurface soil inter-mixed with rocks, that remains frozen for more than a year. They are commonly found in the high latitude areas, specially in and around the polar regions.
The tundra biome is mainly characterized by the presence of permafrost layers. This biome occupies the polar region, where there is less amount of trees and the temperature remains relatively very cold through out the year, favoring the formation of permafrost layers in it.

Answer:
Thymine= 60 ng
Guanine= 20 ng
The complementary base pairing occurs between adenine and thymine and guanine and cytosine bases.
Explanation:
According to the Chargaff rule, a double-helical DNA molecule has an equal number or equal amount of adenine and thymine bases since adenine always pairs with thymine. Similarly, the amount of guanine base is equal to that of the cytosine base.
Chargaff rule is based on the complementary base pairing between purine and pyrimidine bases. According to the given information, the amount of adenine is 60 ng. Therefore, the cell would have 60 ng thymine. Similarly, the amount of the cytosine base in the cell is 20 ng which means that the cell would have 20 ng of guanine base.
According to Chargaff's rules, the amount of adenine is equal to the amount of thymine, and the amount of cytosine is equal to the amount of guanine in a DNA molecule. Thus, the cell should have 60 ng of thymine and 20 ng of guanine.
The question refers to the base pairing rules in DNA, which were discovered by Erwin Chargaff and are now known as Chargaff's rules. According to these rules, the amount of adenine (A) in DNA is always equal to the amount of thymine (T), and the amount of cytosine (C) is always equal to the amount of guanine (G).
In this case, if the DNA analysis reveals that the cell has 60 ng of adenine, the cell should also contain 60 ng of thymine according to Chargaff's rules, since A = T. Similarly, if the cell contains 20 ng of cytosine, there should be 20 ng of guanine as well, because C = G.
So, based on the base pairing rules in DNA, the cell should have 60 ng of thymine and 20 ng of guanine.
