$The ratio of adenine (A) to thymine (T) bases is given as $5:3$. This means for every 5 adenine bases, there are 3 thymine bases.$

\[ 2^3 \times 3 = 8 \times 3 = 24 \]
The least common multiple of the cycle lengths is $\boxed{24}$.**Question:
A bioinformatician analyzing genetic sequences finds that the ratio of adenine (A) to thymine (T) bases in a DNA sample is $5:3$. If there are 15 adenine bases, how many thymine bases are there?
Let the number of thymine bases be $x$. According to the ratio:
\frac{5}{3} = \frac{15}{x}
To solve for $x$, cross-multiply:
