In a certain DNA molecule, the composition is 30% thymine (T) and 20% cytosine (C). If the total number of nucleotides is 500, how many thymine bases are present?
Question
In a certain DNA molecule, the composition is 30% thymine (T) and 20% cytosine (C). If the total number of nucleotides is 500, how many thymine bases are present?
Solution
To find the number of thymine bases, we need to apply the given percentage to the total number of nucleotides.
Step 1: Convert the percentage of thymine into a decimal. 30% becomes 0.30.
Step 2: Multiply the total number of nucleotides by the decimal.
So, 0.30 * 500 = 150.
Therefore, there are 150 thymine bases present in the DNA molecule.
