In cases of skin cancer that are associated with overproduction of EGFR, treatment with antibodies against the extracellular portion of EGFR has been successful. Propose a model to explain how the antibody therapy most likely interferes with the cell signaling pathway, and give ONE reason the therapy is effective for treating cancer.

answer; both surfaces of the membrane are nonpermeable

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.'
