Multiple choice: which of the following statements is not correct, coding sequences for gene products can be isolated from cdna libraries. *e. they stop synthesis at a specific site, so the base at that site can be determined. Molecular genetic analysis and biotechnology ddttp reaction ddgtp reaction ddctp reaction ddatp reaction: a fragment of dna is cloned into a plasmid with a sequencing primer binding site. After dideoxy sequencing, the gel pattern shown in this diagram is obtained. 5" gctagca 3: 5" acgatcg 3, 5" tgctagc 3, 5" cgatcgt 3, before sequencing, the dna fragment was cloned into a plasmid. On the strand that acted as the template in the sequencing reaction, what base of the cloned fragment was closest to the primer: g. A: c, t, mario capecchi, sir martin evans, and oliver smithies recently won a nobel. Prize for gene targeting (gene knockouts) in mice. Most of the dna in this species is noncoding repetitive dna.
