QUESTION 3 3.1
A scientist conducted an investigation on digestion, involving gastric juice. She
compared the time taken for 50 g of different cooked egg samples to form chyme in the
stomach, with the time taken for the same sample to form chyme in a test tube
containing gastric juice. The test tube was maintained at 37°C.
The results are indicated in the graph below.

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.'
