How do restriction enzymes "know" where to cut DNA

• A specific sequence of nucleotides

• They cut randomly

• Distance from the centromere

"Sticky-ends" are DNA strands with:

• single-stranded ends

• ends cut flat by an enzyme

• no way to be recombined

Which is used to cut DNA molecules at specific points?

• gel electrophoresis
• PCR analysis
• a restriction enzyme
• recombinant DNA

molecular scissors that "cut' DNA

• plasmid
• restriction enzymes
• recombinant DNA
• gene

How do scientists cut DNA into smaller strands?

• restriction enzymes
• scissors
• ligase
• agarose
