Question

The number of possible messages contained in a DNA molecule with 5 nucleotides is​

Answer 1

Answer:

are you not sleeping at night

Answer 2

Answer:

One complete turn of the double helix is 3.4 nm long and each of which has 10 base pairs. A nucleotide is made up of sugar, the nitrogenous base and phosphate moiety and each nucleotide base of one strand is paired in the same plane with a base of the other strand. Therefore, there are total 10 x 2= 20 nucleotides in one complete turn of the double helix which is 3.4 nm long. Hence a DNA strand of 340 nm would have 20/3.4 × 340 = 2000 nucleotides. This makes option A correct.
