A red blood cell is 7.5 µm in diameter. It is magnified 2000 times. Calculate the diameter of the image seen through the microscope in millimetres.

15 mm

Explanation:

Given that,

The diameter of a RBC = 7.5 µm

It is magnified 2000 times.

We need to find the diameter of the image seen through the microscope in millimeters.

The size of the diameter is given by :

So, the diameter of the image seen through the microscope is 15 mm.

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."

answer:

sequence 1- deletion

                  2- duplication

                  3- insertion

                  4- substitute

                  5- inversion
