Correct statements about RAPD’s

A. RAPD polymorphism is detected by using oligonucleotides usually more than 10 bases long of random sequences as primers in a reaction.

B. In a strain which has in genomic DNA sequences complementary to the primer oligonucleotide, PCR products will be detected in the gel,

C. Typical RAPD markers show limited variation between parents, especially in naturally inbreeding species.

D. RAPDs are more sensitive than RFLPs to experimental conditions making them more difficult to be consistent and reproducible.
