Making New Cells and Organisms
Students must know...
- The structure of the duplicated chromosome.
- The events that occur in the cell cycle (G1, S, G2, M).
- The role of cyclins and cyclin-dependent kinases (CDKs) in the regulation of the cell cycle.
- Ways in which the normal cell cycle is disrupted to cause cancer, or halted in specialized cells.
- The features of mitosis that result in the production of genetically identical daughter cells including: replication, alignment of chromosomes, and separation of chromosomes.
- What apoptosis means and why it is important to normal functioning of multicellular organisms.
- The difference between asexual and sexual reproduction.
- The role of meiosis and fertilization in sexually reproducing organisms.
- The importance of homologous chromosomes to meiosis.
- How the chromosome number is reduced from diploid to haploid in meiosis.
- Three events that occur in meiosis but not mitosis.
- The importance of crossing over, independent assortment, and random fertilization to increasing genetic variability.
- Terms associated with genetics problems: P, F1, F2, dominant, recessive, homozygous, heterozygous, phenotype, genotype.
- How to derive the proper gametes when working a genetics problem.
- The difference between an allele and a gene.
- How to read a pedigree.
- How to use data sets to determine patterns of inheritance.
- How the chromosome theory of inheritance connects the physical movement of chromosomes in meiosis to Mendel's laws of inheritance.
- The unique pattern of inheritance in sex-linked genes.
- How alteration of chromosome number or structurally altered chromosomes can cause genetic disorders.
- How inheritance of mitochondrial DNA are exceptions to standard Mendelian inheritance.
