4. Discussion Sections (“Labs”) Discussion of homework problems Quizzes Turn in homework Discussion sections will meet this week!
5. Grading: Two lecture exams 200 points Final exam ( Comprehensive!) 100 points Homework (best 5 of 6) 50 points Quizzes (best 5 of 6) 50 points 400 points
6. Make-up Exam: The third exam is an in class make-up exam for students who missed an exam due to an excused absence. There will be no other make-up exams. The make-up may not substitute for the final. Students may also take the make-up exam to replace a lecture exam score but in this case the make-up exam must count toward the final grade.

9. Incarceration rate by gender (from http://www.ojp.usdoj.gov/bjs/prisons.htm ) : Men are ten times as likely as women to be in prison. But, incarceration rate is increasing faster among women than among men (from 2003 to 2004, 2.9% increase for women, 2.0% increase for men).
10. Genetics: The Science of Inheritance Genotype (Inherited traits) Environment Phenotype (Actual characteristics of organism)
17. Functions of DNA: Replication (preserves genetic information) Gene expression (information in genes expressed as protein for cell functions)
18. (Fig. 1.6) DNA replication depends on base-pairing and preserves the sequence of bases
19. Gene Expression: The process by which genes affect the phenotype. Converts sequence of nucleotides to sequence of amino acids in a protein, via transcription and translation.
31. Replication of a chromosome in a diploid (n=1) during mitosis (see Fig.2.10) G1 S G2 After cytokinesis Both daughter cells still diploid! 2n 2c 2n 4c 2n 2c
34. Note! At metaphase in mitosis, all chromosomes line up individually on the metaphase plate, and the chromatids separate and move to opposite poles as independent chromosomes.
38. Chromosomes in Meiosis (in a diploid, see Fig. 2.10) 2n, 2c 2n, 4c 1n, 2c 1n, 2c Meiosis I: Reduction division Tetrad Two copies of same chromosome
42. Genes in Meiosis Meiosis I: Reduction division Two copies of chromosome, with -globin alleles H h Let H= normal -globin Let h=sickle cell -globin
