Worked Solution & Example Answer:DNA probes are short fragments of DNA that A - Scottish Highers Human Biology - Question 7 - 2018
Step 1
C. are used to detect specific sequences in samples of DNA
Answer
DNA probes are specifically designed short sequences that are complementary to the target DNA sequence of interest. They are primarily used in various molecular biology applications, such as Southern blotting and fluorescence in situ hybridization (FISH), to detect the presence of specific DNA sequences in samples. By binding to their complementary sequences, DNA probes help identify and characterize genetic material, making option C the correct answer.
