The test: to understand if the actn3 protein affects running ability, researchers conducted a test. they recruited a group of competitive runners and measured the level of actn3 protein molecules each runner had in their bodies. then, they had the runners participate in a sprint (a short-distance run). during the test, the runners sprinted as fast as they could for 100 meters. evidence: scientists found that the runners who sprinted the fastest had the highest amount of actn3 protein molecules in their bodies. do you think that this evidence shows that the actn3 protein determines running ability? explain your ideas using the words protein, trait, and feature in your response. ​

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.'
