The gene that produces the enzyme placental alkaline phosphatase in humans starts at position 232 million on chromosome 2 (which is 242 million bp long). a. Draw a single copy of chromosome 2 in un-replicated form (one chromatid). Note that chromosome 2 is submetacentric (centromere is near the middle, but closer to the beginning). Indicate the location of the placental alkaline phosphatase (PLAP) gene.
b. PL4P has two common alleles, let's call them. P. and Pz. Draw your homologous chromosome 2 pair assuming you have one copy of both alleles.

Scientists are conducting a study on the effectiveness of a new drug on memory loss. they are giving some of the test subjects the new drug to find out if it improves their long-term memory. which are possible limitations of this study? check all that apply. a) test subjects may want to participate in additional experiments. b) test subjects may think they should be paid more. c) test subjects may get bored and want to quit early. d) test subjects may have to travel during the experiment. e) test subjects may have full-time jobs. this is multiple choice. you for the !
