The percentage of thymine (T) in a given segment of double-stranded DNA is 36/%36%36, percent.

What are the percentages of the remaining nucleotides?

Adenine-36%

Guanine-14%

Cytosine-14%

Explanation:

DNA is made up of two long polynucleotide chains, each called strands. The four nucleotides that make up the DNA molecule are Adenine (A), Guanine (G), Cytosine (C) and Thymine (T).

According to Chargaff in his complementary base pairing rule, Adenine always hydrogen bonds to Thymine while Guanine always pairs with Cytosine i. e. A-T, G-C. Chargaff also stated that in the DNA strand, the amount of purine bases (Adenine and Guanine) is always in an equal proportion with pyrimidine bases (Thymine and Cytosine) or simply put the amount of Adenine equals the amount of Thymine and the amount of Guanine equals the amount of Cytosine. A=T + G=C = 100%.

Based on this, if a DNA molecule has 36% Thymine, it automatically means the percentage of Adenine will also be 36%. Hence, we have A+T = 72%.

The remaining percentage to be shared among Guanine and Cytosine is 100 - 72 = 28%

Since G=C, Each base will contain 28/2 = 14%. Hence, Guanine is 14% while Cytosine is also 14%.

The percentage of the other nucleotides are Adenine (36%), Guanine (14%), and Cytosine (14%).
