Genetic Evolution
Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how gene…
Question

Explain the role of TdT in generating diversity by adding N nucleotides

Expert Solution
Check Mark
Step 1

TdT is known as terminal deoxynucleotidyl transferase.  It is a DNA polymerase that are found in the immature pre - B and T cells.  The role of TdT is to insert the N nucleotides in the V (D)  J segment of the gene.  This is the process done during the rearranging of the genes.
