Friction is the force that one surface exerts on another when they rub together. Friction works in the direction opposite to the motion, causing the object to slow down. What is one way you could reduce the friction between two surfaces?

answer; ///the correct answer to the above statement is (cytoskeleton);

thats not even an aswer choice

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.'
