4. You are supplied with the following information about a DNA molecule: . The molecular weight of a typical nucleotide is 660 Da. . The linear density of double stranded DNA is 4 x 10 Da per micrometer. . There are 10 base pairs in one complete turn of the double helix. Answer the following questions about a DNA molecule with a length of 3.3 micrometer and a base composit contains 20% of the base adenine (A). (a) How many phosphor atoms are present in this DNA molecule? (b) How many full turns of the DNA helix are there in this molecule? (c) What is the percentage of guanine bases in the DNA molecule? (d) How many hydrogen bonds are there in the molecule? (e) How many phosphodiester bonds are there in the molecule? (f) What is the length of a DNA molecule that contains 606 full turns of the double helix?

Explanation / Answer

DNA has length of 3.3 micrometer

length of one base pair is of 3.4 angstrom i.e. 0.00034 micrometer

Therefore it contain 9705 base pairs.
