Among biotechnology applications,gene therapy and genetic engineering are similar,except that

A) a human receiving gene therapy in the somatic cells could not pass on the new alleles to children.
B) there is no genetic difference between transgenic organisms and humans having had gene therapy.
C) the genetic sequences transferred in gene therapy are from human to human.
D) genetic engineering requires DNA sequencing to identify the genes, while human gene therapy does not.
E) Both answers, regarding the human-to-human gene transfer, and the human with gene therapy not passing on genes to children are correct.
