1 Name: Test date: Per: Cell Cycle/Protein Synthesis Unit 1 Study Guide Always remember to use your notes/lectures first, then book, then other sources to help you find the right answers. Be as thorough and specific as possible there is a direct correlation between your effort/complete answers and how well you perform on tests! You are responsible for learning the material. 1) What happens during each of the three parts of interphase? 2) What is mitosis? Why do cells go through mitosis? 3) Describe the four stages of mitosis. Prophase Metaphase Anaphase Telophase 4) What happens during Cytokinesis? 5) Mitosis starts after and ends before 6. Meiosis produces cells with how many chromosomes in humans? 7. What type of cells are haploid cells? 8. Two similar chromosomes that you inherit from your parents (one from your mother, one from your father) are called what? How many pairs of these chromosomes do humans have? 9. What happens to sister chromatids in meiosis II? 10. What does meiosis produce?

In addition to knowing all the parts of the cell cycle, mitosis, and meiosis you will be responsible for defining the following vocabulary: Interphase, identical daughter cells, zygote, homologous chromosomes, crossing over, diploid, haploid, genetic recombination, oogenesis, chromosome, chromatid, tetrad, gametes, polar bodies, sexual reproduction, asexual reproduction, centromere, karyotype, non-disjunction, REVIEW: Protein synthesis: Use your notes, Ch. 8.4 and 8.5 to help you answer the following: 1. Which process happens first--transcription or translation? Why? 2. List and describe ALL the stages of transcription and translation (INCLUDE labeled diagrams): 3. Write the nucleotide sequence of the RNA strand that would be complementary to the following DNA strand: GTAGTCA. 4. What is the term for a three-nucleotide sequence that codes for an amino acid? 5. Figure 8.2 on the next page shows a single strand of DNA. Write the first three nucleotides of the complementary RNA strand. 6. Describe translation. 7. What is the main function of trna? 8. How many amino acids are coded for by the strand of mrna shown below? Assume the reading frame begins with the first nucleotide. CGAUAC 9. What are the three main differences between DNA and RNA? Using the following DNA sequence, what are the amino acids that would be in this protein? TACGCGGCTGTGAAA 10. What process is shown to right (Ch. 8)? 11.
