(a)

Summary Introduction

To determine: The way by which deletion within the GAL4 gene would affect transcription of the yeast GAL1 gene in the presence of galactose.

Introduction: Transcription is the process of formation of RNA (ribonucleic acid) from the complementary DNA (deoxyribonucleic acid). GAL genes are required for the proper growth of yeast in galactose medium. The regulation of GAL genes is regulated by the products of GAL4, GAL8, and GAL3 genes. Mutation in these regions may disrupt the process of transcription in yeast.

(b)

Summary Introduction

To determine: The way by which deletion within the entire GAL3 gene would affect transcription of the yeast GAL1 gene in the presence of galactose.

Introduction: As mentioned in the concept introduction part a.

(c)

Summary Introduction

To determine: The way by which deletion of a mutation within the GAL80 gene that blocks the ability of Gal80 protein to interact with Gal3p would affect transcription of the yeast GAL1 gene in the presence of galactose.

Introduction: As mentioned in the concept introduction part a.

(d)

Summary Introduction

To determine: The way by which deletion of one of the four UASG elements upstream from the GAL1 gene would affect transcription of the yeast GAL1 gene in the presence of galactose.

Introduction: As mentioned in the concept introduction part a.

(e)

Summary Introduction

To determine: The way by which a point mutation in the GAL1 core promoter that alters the sequence of the TATA box would affect transcription of the yeast GAL1 gene in the presence of galactose.

Introduction: As mentioned in the concept introduction part a.

Find out about the organisations and the movements aimed at the conservation of our natural resources. Eg Chipko movement and Greenpeace. Make a project report on such an organisation.
What are biofertilizers and mention the significance
PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen.     How would increased estrogen affect the river otter population? Based on your reading of the materials in this unit, what factors can affect fertility in humans?   Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.
