the diagram shows a section of double stranded DNA, and includes the bonds that hold the two strands together. Chemical bonds are represented by dotted lines (label 1) and solid lines (label 2). Which types of bonds are represented by the dotted lines and the solid lines in the diagram?

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
