A probe which is a molecule used to locate homologous sequences in a mixture of DNA or RNA molecules could be:

a. An ssRNA
b. An ssDNA
c. Either RNA or DNA
d. Can be ssDNA but not ssRNA

Answers (1)

The answer is the option (c) 

Explanation: A probe is a specific type of molecule designed to locate and bind to homologous sequences within a complex mixture of DNA or RNA. These probes play a crucial role in molecular biology and genetic research by enabling scientists to identify and isolate specific sequences of interest. Probes can be constructed from either RNA or DNA, depending on the experimental needs and the target sequences. By hybridizing with complementary strands in the sample, the probes facilitate the detection and analysis of genetic material, aiding in various applications such as gene expression studies, genetic sequencing, and diagnostic testing.
