2. Explain what mitosis and meiosis are and where in the body and for what purposes these
cells processes happen.
3. Describe the differences and similarities between a body cell and a sex cell (sperm and egg).
4. Using a Punnett square, determine the probability of an offspring inheriting a trait.
5. Understand the difference between genotype and phenotype. (Sesame Street Genetic;
6. Identify possible genotype of organisms (both real and imaginary) by examining their phenotypes.
7. Explain the relationship among these: chromosome, DNA, chromatid, gene, nucleotide, and
nitrogen bases.
8. Describe the structure of the DNA molecule.
9. Label a diagram of an unraveling chromosome with these labels: DNA, chromosome, gene, and
10. Demonstrate a basic understanding of protein synthesis by constructing a portion of a DNA
molecule (gene) that codes for a specific human protein.
11. Explain why genes come in pairs.
12. Explain that the genetic code is carried by 4 different nitrogen bases within the structure of DNA’s
“ladder” shape.
13. Show how DNA sends the genetic code to RNA to assemble amino acids into proteins.
