The human body is said to contain approximately 50.0 grams of DNA in the entire body. If the number of nucleotides in ONE STRAND of DNA is approximately 3.0 x 106, and the average molar mass of a nucleotide is 327 g/mol, what is the average molar mass of an entire DNA double helix?
Here is the equation provided:
14 C5H10O4 + 4 C5H5N2O2 + 4 C5H5N5 + 3 C5H5N5O + 3 C4H5N3O + 12 H3PO4 → C137H178O106N52P12 + 12 H2O + 12 H2
d-ribose thymine adenine guanine cytosine 14 nucleotide DNA
double helix
To find the average molar mass of an entire DNA double helix, we can calculate the total number of nucleotides in one DNA double helix and then multiply it by the average molar mass of a nucleotide.
Given:
Mass of DNA in the entire body = 50.0 grams
Number of nucleotides in one strand of DNA = 3.0 x 10^6
Average molar mass of a nucleotide = 327 g/mol
To find the number of nucleotides in one DNA double helix, we multiply the number of nucleotides in one strand by 2:
Number of nucleotides in one DNA double helix = 3.0 x 10^6 * 2 = 6.0 x 10^6
Now, we can calculate the average molar mass of an entire DNA double helix by multiplying the number of nucleotides in one DNA double helix by the average molar mass of a nucleotide:
Average molar mass of an entire DNA double helix = 6.0 x 10^6 * 327 g/mol = 1.962 x 10^9 g/mol.
Therefore, the average molar mass of an entire DNA double helix is 1.962 x 10^9 g/mol.
To find the average molar mass of an entire DNA double helix, we need to calculate the total number of nucleotides in the DNA double helix and then use this information along with the molar mass of a single nucleotide.
First, let's calculate the total number of nucleotides in the DNA double helix. Since DNA consists of two strands, the number of nucleotides in one strand will be equal to the total number of nucleotides in the DNA double helix.
Given that the number of nucleotides in one strand is approximately 3.0 x 10^6, we can assume that the total number of nucleotides in the DNA double helix is also 3.0 x 10^6.
Next, we need to calculate the total molar mass of the nucleotides in the DNA double helix. The average molar mass of a nucleotide is given as 327 g/mol.
To find the total molar mass, we can multiply the molar mass of a single nucleotide (327 g/mol) by the total number of nucleotides (3.0 x 10^6):
Total molar mass = Molar mass of a single nucleotide x Total number of nucleotides
= 327 g/mol x (3.0 x 10^6)
Now, let's calculate the total molar mass:
Total molar mass = 327 g/mol x 3.0 x 10^6
= 9.81 x 10^8 g/mol
Therefore, the average molar mass of an entire DNA double helix is approximately 9.81 x 10^8 g/mol.
