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.

The correct answer is option A
Auxin promotes cell elongation and cell division in stems. They promote stem elongation and inhibits the growth of lateral buds.
This plant hormone is produced in the stem tip and then it travels to the darker side of the plant so that the cells in the darker side grows more than the cells in the lighter side of the plant.

The downfall of a tragic character is the result of "a tragic flaw".
The term hero is gotten from a Greek word that implies a man who faces affliction, or shows strength, despite risk. Nonetheless, at times he faces ruin too. At the point when a hero goes up against destruction, he is perceived as a tragic hero. Aristotle, the Greek philosopher, portrays these plays or stories, in which the principle character is a shocking saint, as disasters. Here, the hero goes up against his ruin whether because of destiny, or by his own oversight, or some other social reason.
Hamartia refers to a tragic flaw that causes the downfall of a hero.
Answer:
Option B
Explanation:
In almost all the literature forms specially in greek literature, a hero has always been a person who has rises against all the odds in his/her life. This special character faces affliction and usually shows strength instead of the risk involved in it. Some time this character undergoes complete down fall or he/she get ruined but this "hero" rise up again and stand strongly against the destruction and thus is perceived as a tragic hero. Aristotle, has always portrayed in his writing "hero" as the main character who get ruined because of destiny or some social reason
Hence, option B is correct
