HW2: Chromosomes, Cell Division by mitosis; Campbell pages 128, 130, 138-139
1. What is a chromosome made of? (p.128, 130) What is chromatin?
2. Describe the relationship between the following pairs:
a. Chromosome, sister-chromatids (p.130)
b. A Pair of two sister-chromatids (p.130)
c. A Pair of two homologous chromosomes (p.139)
d. Chromosome, genes (p.130)
e. Gene and locus (p.139)
f.
Sex chromosomes, autosomes (p.139)
3. Draw Figure 8.12 on page 139. In addition to the given information, mark – which two chromosomes are
homologous? Where are the genes?
4. What is the purpose of cell division by mitosis? Describe three different purposes. (p.131, 138)
5. Observe Figure 8.11B in page 138. How are dividing cells different from other cells that are alive but not dividing?
6. Human body cell normally have 46 chromosomes. How many chromosomes will be in human cells right after
mitosis? Explain.
