Box Turtles. Suppose you want to know how many box turtles there are in a wooded park. On the first day, you hunt through the woods and capture 18 turtles. You place a spot of paint on each turtle’s shell and release all turtles back where you found them. A week later you return, and with hard work and effort, catch 50 turtles. Of these, 10 are marked and 40 are unmarked. Since you know how many turtles you marked, sampled, and recaptured, you can estimate the size of the whole population. By the definitions above, M =18 marked and released; S = 50 in the second sample; and R =10 recaptures.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
