XML AND ADO.NET QUIZ

always contains an origin of replication

is a circular DNA molecule

usually contains one or more restriction sites

All of these

Protein-coding genes are always associated with a restriction pattern

Restriction sites allow DNAs to be digested

None of these

Known protein coding sequences are too far apart to allow linkage determination for most new genes

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

digest with RNase, add G residues to the 3' end, treat with reverse transcriptase, add G residues to the 3' end and 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

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