1.DNA is the genetic molecule of life. What is your evidence that DNA is the molecule of inheritance?
Scientists were able to produce a giant mouse through use of human or rat growth hormone and the production of pigs with leaner meat from use of bovine or human growth hormone. Other research involved clinical trials on gene transfer in cancer and other disease treatment. Is this type of research beneficial?

4. Two heterozygote tongue rollers (dominant trait) have a child. What percentage of individuals would be predicted to be heterozygotes, homozygous dominant and homozygous recessive? What is the only genotype of two parents that would ensure that their offspring could not roll their tongue (recessive trait)? Explain your reasoning.
5. List the stages of meiosis I and meiosis II, indicating the point at which the cell becomes haploid. Why does it become haploid at this point?
