Max wants to see if mice that are fed food A grow faster than mice that are fed food B. He measures the mass of the mice each day. He feeds each group the same amount of food at the same time each day. What is the dependent
variable?
food A
food B
mass of mice
amount of food

ans.

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.'
