What is the genetic basis for lactose intolerance in humans? A) a change in nucleotide sequence of the lactase gene
B) a change in nucleotide sequence outside of the lactase gene
C) a change in nucleotide sequence of the lactase RNA
D) a change in the amino acid sequence of the lactase enzyme

i think its through the fallopian tube

my teacher would say no s

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.'
