A culture of bacteria not resistant to tetracycline develops an infection from a virus that is derived from the lysis of tetracycline-resistant bacteria.
Scriver, pp 5587–5628. Sack, pp 3–29. ) Normal parents having two affected children, male and female, is suggestive of autosomal recessive inheritance. qxd 11/14/01 10:36 AM Page 29 DNA Structure, Replication, and Repair Answers 29 interpretation fits with the usual inheritance of oculocutaneous albinism (203100), implying a 1/4 risk for a newborn in whom signs and symptoms of albinism are not yet evident. The defect in melanin synthesis in albinism decreases the amount of this protective pigment in skin and increases the exposure of DNA in skin cells to sunlight.
