One of the unique proteins found in the meiotic cohesion complex is Rec 8. This protein, expressed only during meiosis, is not cleaved during meiosis I but is cleaved during meiosis II to finally allow sister chromatids to segregate. Scientists hypothesized that a protein protects the Rec 8 protein from cleavage and degradation during meiosis I. To identify such a protein, researchers first produced the Rec 8 protein in mitotically dividing yeast cells. In these cells, Rec 8 was cleaved during mitosis and the cells suffered no harmful effects. To find a protein that protects Rec 8 from cleavage, researchers then expressed other proteins in the cell expressing Rec 8 mitotically and were able to identify Shugoshin that protects Rec 8 from degradation. What effect do you think expressing Shugoshin had on the mitotically dividing cells expressing Rec 8? What phenotype would the cells show?

What property of a water molecule allows it to: form hydrogen bonds?

Let f be defined on $R^2$. If $\lim _{(x, y) \rightarrow(a, b)} f(x, y)=L$ and if the one-dimensional limits $\lim _{x \rightarrow a} f(x, y)$ and $\lim _{y \rightarrow b} f(x, y)$ both exist, prove that $\lim _{x \rightarrow a}\left[\lim _{y \rightarrow b} f(x, y)\right]=\lim _{y \rightarrow b}\left[\lim _{x \rightarrow a} f(x, y)\right]=L$. Now consider the functions f defined on $R^2$ as follows: (a) $f(x, y)=\frac{x^{2}-y^{2}}{x^{2}+y^{2}}$ if $(x, y) \neq(0,0), f(0,0)=0$. (b) $f(x, y)=\frac{(x y)^{2}}{(x y)^{2}+(x-y)^{2}}$ if $(x, y) \neq(0,0), f(0,0)=0$. (c) $f(x, y)=\frac{1}{x} \sin (x y)$ if $x \neq 0, f(0, y)=y$. (d)

$$f(x, y)=\left\{\begin{array}{l}{(x+y) \sin (1 / x) \sin (1 / y)} \\ {0}\end{array}\right.$$

if $x \neq 0$ and $y \neq 0$, if $x = 0$ or $y = 0$. (e)

$$f(x, y)=\left\{\begin{array}{l}{\frac{\sin x-\sin y}{\tan x-\tan y}} \\ {\cos ^{3} x}\end{array}\right.$$

if $\tan x \neq \tan y$, if $\tan x=\tan y$. In each of the preceding examples, determine whether the following limits exist and evaluate those limits that do exist: $\lim _{x \rightarrow 0}\left[\lim _{y \rightarrow 0} f(x, y)\right] ; \quad \lim _{y \rightarrow 0}\left[\lim _{x \rightarrow 0} f(x, y)\right] ; \quad \lim _{(x, y) \rightarrow(0,0)} f(x, y)$.
