True False Section _____C-False 1. DNA is positively charged due to the phosphate group. _____A-True 2. A phage attacks bacteria and replicates inside of the bacteria. _____A-True 3. DNA can be circular in the form of a plasmid for bacterial transformation. _____A-True 4. Avery and Griffith were responsible for transformation of mice with smooth and rough colonies of bacteria to show DNA was the transformable material. _____A-True 5. Hershey and Chase were responsible for showing DNA was the material in phages that was injected into bacteria or archaea. _____A-True 6.

  1. Determine if the genetic offspring child could be born from the blood type mating with the listed parents. Parents Child-Born Yes/No Circle one a) Type A x Type AB Type B Is it possible? Yes No A B a natural born child (not adopted) is possible for them to have as their own child….. A A A B A
  2. Hemophilia is a sex-linked gene where the affected child carries an X h^ and has a bleeding problem due to too low of a platelet count so that the blood is unable to clot- they bleed to death Carriers are heterozygotes and can clot- they do not bleed to death but can pass the gene onto a child Show a Punnett square for the following cross and indicate the F generation phenotypes (sex, clot normally, cannot clot). XH^ X h^ x^ XhY Punnett square Ratio Genotypes Phenotypes Xh^ Y 0 XH^ X H^ Female, normal, normal clotting XH^1 XH^ X h^ Female, carrier, normal clotting 1 Xh^ X h^ Female, hemophiliac, cannot clot 1 XHY Male, normal, normal clotting X h 1 XhY Male, hemophiliac, cannot clot
