Question 16

Adenine pairs with _____________

cytosine

guanine

thymine

uridine

none of the above

Solution

Answer:

13). c. Antiparallel

One strand of DNA runs from 3\'---5\' and ab opposite strand of the same DNA runs from 5\'--3\'. This is called antiparallel.

3\'---5\'

5\'---3\'

14). D. genotype

The genetic constitution of an organism is called genotype.

15). B. uridine

Uracil+ribose sugar = Uridine (nucleoside of uracil)

16). C. Thymine

A=T(in DNA) or A=U (in RNA)

G=U
