What is meant by the term multiple alleles? What is the definition of codominance? 11. How are the ABO blood groups determined? What are the various genotypes and phenotypes? Be able to work out inheritance problems involving these various groups. For example‚ questions 36-39 in the Post Test of Chapter 9 on Blackboard.

Homologous Chromosomes and Sister Chromatids (HC and SC): Clearly distinguish between HC and SC pairs. Your answer should include the following: a clear distinction between ‘chromatin’ and ‘chromosome’‚ and how this difference affects gene expression; simple line diagrams to illustrate the difference between non-replicated and replicated DNA inchromatin and chromosome forms; afull description of both HC and SC with a labeled diagram that includes gene/allele sequences for a heterozygote and ‘m’

Unit 2. Chapters 9-16. Cell Processes 1. Cellular Respiration‚ Photosynthesis‚ Cell Cycle‚ Mitosis‚ Meiosis‚ & Genetics. Note A: All work must be hand-written‚ including charts & diagrams. Note B: each answer requires more than one sentence & use diagrams whenever possible; failure to use diagrams will result in less points. Chapter 9 Outline 1) Principles of Energy Conservation a) Cellular respiration and fermentation are catabolic(energy – yielding) pathways b) Cells must recycle the ATP
Premium Adenosine triphosphate DNA Cell cycle
Chapter 12 Cyclins and cyclin-dependent kinases are regulatory proteins that assist in the cell cycle. Particular protein kinases give the go-ahead signals at G1 and G2 checkpoints. These protein kinases are present at a constant concentration in the cell but are inactive unless in the presence of cyclin‚ these are cyclin dependent kinases. The activity of a cdk rises and falls with the concentration of cyclin. Cyclin levels rise during the S and G2 phases then fall abruptly in the M phase
