Summary Introduction

To explain: The relationship between losing DNA in B and T cells during maturation and DNA as heritable biological information based on similarities between cellular and organismal generations.

Introduction:

The B cells and T cells are types of lymphocytes. They originate from the stem cells as other blood cellsby a process known as hematopoiesis. Some of the lymphocytes move to thymus that matures into T cells. The lymphocytes present in the bone marrow mature into B cells. An antigen binds tothe receptor present on B or T cell and elicits a B cell or T cell response. Unlike other cells of immune system, particular lymphocytes have an antigen receptor specific for one epitope. So, it can bind to antigen of any pathogen that displays that epitope.
