(a)

Summary Introduction

To describe: The effect that is necessary to specify that product concentrations remained negligible during the course of the reaction.

Introduction: The enzyme β-galactosidase catalyzes the hydrolysis of the disaccharide lactose and results in the formation of glucose and galactose. To determine the value of Km and Vmax, the same amount of enzyme was incubated with a series of lactose concentrations under the condition where product concentrations remained negligible.

(b)

Summary Introduction

To describe: The effect when the lactose concentration is doubled by plotting a graph.

Introduction: The enzyme β-galactosidase catalyzes the hydrolysis of the disaccharide lactose and results in the formation of glucose and galactose. To determine the value of Km and Vmax, the same amount of enzyme was incubated with a series of lactose concentrations under the condition where product concentrations remained negligible.

(c)

Summary Introduction

To calculate:  The inverse value of the rate of lactose consumption and lactose concentration by plotting a graph.

Introduction: The enzyme β-galactosidase catalyzes the hydrolysis of the disaccharide lactose and results in the formation of glucose and galactose. To determine the value of Km and Vmax, the same amount of enzyme was incubated with a series of lactose concentrations under the condition where product concentrations remained negligible.

(d)

Summary Introduction

To determine: The value of Km and Vmax from the double reciprocal plot.

Introduction: The enzyme β-galactosidase catalyzes the hydrolysis of the disaccharide lactose and results in the formation of glucose and galactose. To determine the value of Km and Vmax, the same amount of enzyme was incubated with a series of lactose concentrations under the condition where product concentrations remained negligible.

(e)

Summary Introduction

To explain: The graph plot when the value of enzyme used becomes 0.5µg.

Introduction: The enzyme β-galactosidase catalyzes the hydrolysis of the disaccharide lactose and results in the formation of glucose and galactose. To determine the value of Km and Vmax, the same amount of enzyme was incubated with a series of lactose concentrations under the condition where product concentrations remained negligible.

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?
You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.
You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb?  Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
