- Multiple Choice
In which step is the DNA replicated?
- Multiple Choice
In which step does the chromatin begin to condense

- Open QuestionIn this chapter, we focused on how chromosomes are distributed during cell division, both in dividing somatic cells (mitosis) and in gamete- and spore-forming cells (meiosis). We found many opportunities to consider the methods and reasoning by which much of this information was acquired. From the explanations given in the chapter, answer the following questions.How do we know that mitotic chromosomes are derived from chromatin?

We found many opportunities to consider the methods and reasoning by which much of this information was acquired. From the explanations given in the chapter, answer the following questions.How do we know that DNA replication occurs during interphase, not early in mitosis?

- Open Question
Examine the following diagrams of cells from an organism with diploid number 2n=6, and identify what stage of M phase is represented.
- Open Question
Our closest primate relative, the chimpanzee, has a diploid number of 2n =48. For each of the following stages of M phase, identify the number of chromosomes present in each cell.
mitotic metaphase - Open Question
Our closest primate relative, the chimpanzee, has a diploid number of 2n =48. For each of the following stages of M phase, identify the number of chromosomes present in each cell.
early mitotic prophase - Open Question
Our closest primate relative, the chimpanzee, has a diploid number of 2n =48. For each of the following stages of M phase, identify the number of chromosomes present in each cell.
end of mitotic telophase - Open QuestionWhat role do the following cellular components play in the storage, expression, or transmission of genetic information: (a) chromatin, (b) nucleolus, (c) ribosome, (d) mitochondrion, (e) centriole, (f) centromere?
- Open QuestionDiscuss the concepts of homologous chromosomes, diploidy, and haploidy. What characteristics do two homologous chromosomes share?
