(a) To write: Effect of mutation in Bad such that it cannot be phosphorylated on apoptosis. Introduction: Bad gene is both a positive and negative regulator of apoptosis. When non-phosphorylated it binds to Bcl-2 protein and prevents its anti-apoptotic activity. However, a phosphorylated Bad cannot bind to Bcl-2

Summary Introduction

(a)

To write:

Effect of mutation in Bad such that it cannot be phosphorylated on apoptosis.

Introduction:

Bad gene is both a positive and negative regulator of apoptosis. When non-phosphorylated it binds to Bcl-2 protein and prevents its anti-apoptotic activity. However, a phosphorylated Bad cannot bind to Bcl-2

Summary Introduction

(b)

To write:

Effect of overexpression of Bcl-2 on apoptosis.

Introduction:

Bcl-2 is a negative regulator of apoptosis and the overexpression of Bcl-2 blocks the movement of cytochrome-c from the mitochondrial membrane to the cytosol.

Summary Introduction

(c)

To write:

Effect of mutation in Bax gene such that it cannot form homodimers.

Introduction:

Bax if the first pro-apoptotic gene to be discovered. Its sequence is somewhat related to the Bcl-2 and CED-9 gene both of which are known to be the suppressor of apoptosis. However, overexpression of Bax gene can cause cell death.

Summary Introduction

To write:

Which of the mutations discussed above are likely to be present in cancer cells.

Introduction:

Cells that undergo uncontrolled cell division and have the ability to metastasize to other parts of the body are known as cancer cells. These cells have lost the ability to undergo apoptosis as they do not die and keep of dividing.

Discussion entries must be at least 250 words to fulfill the assignment requirements. You must complete your entry before you will be able to see the responses of other students. Responses to other students are encouraged but not required. Grading for discussion entries will be based on application of course concepts, proper grammar, and correct punctuation. Read one the attached article and explore the Human Development Index (https://hdr.undp.org/data-center/human-development-index#/indicies/HDI). In your opinion, is the Human Development Index a good measure of the well- being of the people of a nation? Are the items measured in the HDI valid and relevant in the modern global economy? How are they related to the political economy of a nation? The attached articles propose some alternative measures of well-being. In your opinion, are there other measures of well-being that might be better alternatives to the items in the current HDI?
