Recombinant DNA Technology
An example of a restriction fragment length polymorphism is

an Eco RI cuts DNA at a different sequence than Hind III
different length fragments of DNA resulting from loss or gain of a restriction site
cystic fibrosis results from a three base deletion in most cases but in other cases, other mutations are involved
All of these

The order for the construction of a cDNA fragment from mRNA is to

treat with reverse transcriptase, digest with RNase, add G residues to the 3' end, bind oligo-dC, treat with DNA polymerase and bind oligo-dT
bind oligo-dT, treat with reverse transcriptase, digest with RNase, add G residues to the 3' end, bind oligo-dC, treat with DNA polymerase
bind oligo-dC, treat with reverse transcriptase, digest with RNase, add G residues to the 3' end, bind oligo-dT and treat with DNA polymerase
