What is the function of a restriction enzyme? What is the name for the specific restriction enzyme you will use to digest the gene from the PCR experiment? 2. What is unique about the DNA sequences recognized by restriction enzymes? 3. Why is DNA 'pulled' toward the positive electrode in gel electrophoresis? 4. Which migrates faster in an agarose gel, larger DNA fragments or smaller DNA fragments? 5. What is the difference between a gene and an allele? 6. Polydactyly, extra digits on hands and feet, may be caused by the presence of a dominant allele. A man and a woman who are both heterozygous for polydactyly decide to have children. a. Complete the Punnett-square for a cross between these two individuals. b. What is the probability that their first child will have polydactyly? 7. What is the genotype of a child with type AB blood? Use the allele symbols as given in the lab manual. 8. Why are men considered to be hemi-zygous regarding the sex chromosomes? What is the function of a restriction enzyme?
