A) DNA profiling B) DNA scrutiny C) DNA outline D) DNA fingerprinting - AnswerDNA profiling In order for gene therapy to be permanent, A) the normal gene must first be treated with UV radiation to ensure noninfectivity. B) the defective gene must first be removed from all somatic cells. C) the normal gene must be transferred to somatic cells that can continuously multiply. D) the normal gene must be added to the germ line cells. - Answerthe normal gene must be transferred to somatic cells that can continuously multiply. Which of the following statements regarding DNA is false? A) Current estimates are that there are 20,000 genes in the human genome. B) Scientists think that the typical human gene specifies just one polypeptide. C) Telomeres seem to have a structural function. D) Long stretches of repetitive DNA are prominent at centromeres and ends of chromosomes. - AnswerScientists think that the typical human gene specifies just one polypeptide. Which of the following statements about nucleic acid probes is false? A) A nucleic acid probe is usually labeled with a radioactive isotope or fluorescent tag to help identify its location. B) A nucleic acid probe can be used to find a specific gene. C) A nucleic acid probe is a double-stranded section of DNA. D) A nucleic acid probe binds to a complementary sequence in the gene of interest. - AnswerA nucleic acid probe is a double-stranded section of DNA. The feature of "sticky ends" that makes them especially useful in DNA recombination is their ability to
