Summary Introduction

To determine:

The reason for the loss of DNA in mature B and T cells, focusing primarily on the similarities between cellular and organismal generations.

Introduction:

T cells and the B cells are the cells that provide cellular immunity to the body. These cells posses the receptors or the antibodies that recognize a foreign antigen. This process in turn elicits the immune response of the body.

Bacteriophage is added to a culture of human T cells and none of the human T cells were infected by bacteriophage. Why? T cells do not have the proper protein machinery to carry out transcription and translation of bacteriophage genes.   T cells do not have the corresponding cell surface receptors that are recognized by bacteriophage viruses.   T cells have a thick outer cell wall that blocks bacteriophage infection.   T cells do not carry out DNA replication and thus are not good hosts for the bacteriophage viruses.
Would it be effective to use an inhibitor of RNA polymerase to block the HIV replication cycle and subsequent infection of human T cells? Yes, this would stop the transcription of viral genes and prevent HIV from being able to replicate. No, these types of inhibitors do not exist and would be impossible to make. No, this would block transcription of T cell genes, leading to the death of T cells and compromised immune systems in individuals. Yes, inhibitors of RNA polymerase are easy and relatively inexpensive to produce and make good therapeutics.
B cells are specialized blood cells that secrete antibodies. Normally, human blood has millions of differenttypes of B cells making millions of different kinds ofantibody molecules. This variety occurs because, as described in the Fast Forward Box in Chapter 13 entitledProgrammed DNA Rearrangements and the ImmuneSystem, antibody genes undergo rearrangements in theprecursors of B cells. Individual B cell precursorsrearrange their antibody genes in different ways.In the blood of patients with cancers called B celllymphomas, almost all of the antibody molecules areall of one type, but this single type of antibody isdifferent in different lymphoma patients.a. Based on this information, provide a brief description of the genesis of B cell lymphomas, focusingon the cells that are overproliferating.
