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.

#SCPH01 Biochemistry

Statement: AFLP shares some features of both RFLP and RAPD analyses.

Explanations: I. It uses restriction enzyme-digested genomic DNA as template for PCR amplification using primers that contain the restriction enzyme recognition sites plus a number of, usually 2-3, arbitrary nucleotides.

II. AFLPs are faster, less labour intensive and provide more information than RFLPs, and they are highly reproducible, which is a great advantage over RAPDs.

#SCPH01 Biochemistry

The genomic DNA of an organism is digested with two restriction enzymes; one of the, PstI (CTGCA/G), while the other., MseI (T/TAA). This would generate the following 3 types of DNA fragments: 

(1) both ends cleaved by PstI (Pst-Pst), 

(2) both ends cleaved by MseI (Mse-Mse), and 

(3) one end generated by each of the two enzymes (Pst-Mse).
