Chapter 3, Problem 65P
Summary Introduction
To determine: The unusual features that distinguishes this pedigree from other pedigree charts.
Introduction. Mitosis is the equational division where the diploid cell divides to form two daughter cells that are also diploid in three. The process is divided into four phases that bring about the nuclear division and distribution of chromosomes into two daughter cells that are identical to the parent cells.

Encircle the cell and label the specific stage in the meiosis it displays. Identify as many as you can
witha minimum of two cells representing different stages. Make sure to specify whether the stage
belongs to meiosis I or II. If you identify a cell at prophase I, then specify the substage.
For fruit flies, N=4 and 2N=8
a. Sketch a dividing fruit fly cell which is in prophase I.
b. Sketch a dividing fruit fly cell which is in metaphase of mitosis.
A 35 year old man developed increasing pain in his left thigh and a marked limp, over 3 weeks. Five years he had undergone a nephrectomy for a renal carcinoma. An isotope showed metastasis in his right lateral ribs and left femur and he had been taking sunitinib. Assuming you are the attending physician, what is the most appropriate next step in his management?

Mitosis must be carefully regulated to ensure the normal distribution of chromosomes to the
daughter cells. A ring-shaped protein molecule known as cohesin attaches to the centromere
of a chromosome and holds sister chromatids together to prevent their premature separation.
Enzymes detach cohesin molecules from the centromere immediately before the sister
chromatids segregate.
-based on Nature, 2006
In which of the cells labelled in the diagram above are enzymes most likely acting to detach cohesin molecules from the centromere?

A haploid S. cerevisiae mes. When certain haploids come into contact, they fuse their cell walls and membranes, followed by the fusion of their nuclear membranes. The single nucleus now has 32 chromosomes, 16 from each parent strain, and is thus a diploid. Haploid yeast strains divide mitotically to give rise to haploid progeny, and diploid strains divide mitotically to give rise to diploid progeny. Certain haploids can fuse to form diploids. Haploid S. cerevisiae exists in two "mating types," called a and a Mating occurs only between a and a cells; no mating occurs between cells of identical mating type.
