During replication, you must find the complementary DNA strand that matches.
In DNA, the code letters are A, T, G, and C, which stand for the chemicals adenine, thymine, guanine, and cytosine, respectively. In base pairing, adenine (A) always pairs with (T) thymine, and (G) guanine always pairs with (C)cytosine.
The greater the difference between the dry bulb temperature and the wet bulb temperature, the drier the air is. From the air temperature and the wet bulb temperature, the relative humidity of the air can be easily found.
