Question

How can your body make so many different antibodies (proteins) from just a select set of genes? (Please type answer and use proper complete sentences to give a well thought out answer.)

Answer 1

Gene is the part of DNA that contian all the information for the to do translation( formation of protiens).The haevy chain and light chains are are paired with each other to form a complete antibody having many and many antigen binding site.Antibodies are produced form ools of genes segments.Antibodies are actually produced by the WBC's ,specifically B-lymphocytes.When the antigen bind on surface B-lymphocytes , the B-lymphocyte cells starts division and mature into a group of similar or ideantical cells called antibodies. Our body can make so different types of antibodies because this variability hasbeen decided by the genes of T cells or B cells. Due the reason that both the Tcells and B cells conatains the genes for the formation of antibodies. So they can form the many different regions of light and heavy chains by rearrangement of their DNA.The fact is that a single antibody gene can form an antibody which is capable of forming millions of 3-dimensional structure and can combine with the antigen .
