A cell has an internal concentration of sodium chloride equal to 9 g/L. A sodium chloride (NaCl) solution was prepared in a lab at a concentration of 8 g/L. Which of the following describes the effect of placing the cell in this solution?

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."
