Give one word for the following:
Technique used to detect hybridisation of a radiolabelled probe to its complementary uncleotide sequence on a photographic film.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for a single word that describes a technique used to detect the hybridization of a radiolabeled probe to its complementary nucleotide sequence on a photographic film.

2. **Identifying Key Terms**: The key terms in the question are "hybridization," "radiolabeled probe," "complementary nucleotide sequence," and "photographic film."

3. **Defining Hybridization**: Hybridization refers to the process where two complementary strands of nucleic acids (like DNA or RNA) bind together. In this context, it involves a radiolabeled probe binding to a complementary nucleotide sequence.
