A fragment of DNA contained 144 nucleotide base pairs - Scottish Highers Human Biology - Question 4 - 2018

In a DNA fragment, each nucleotide base pair consists of two nucleotides. Since there are 144 nucleotide base pairs, the number of nucleotides is:

$144 ext{ base pairs} \times 2 = 288 ext{ nucleotides}$

Each nucleotide contains one deoxyribose sugar, so the total number of deoxyribose sugars is also 288. Therefore, the answer is:

D. 288
