Below is the final functional kappa light-chain protein produced from germline DNA for the kappa light-chain in humans in a mature B-cell. V2 J3 C Below is a portion of the germline DNA for the kappa light-chain in humans. The intervening sequence is denoted by a horizontal line. For each step in the process of generating the above light-chain protein from the germline DNA below, determine if the corresponding DNA or RNA sequences would be present or absent in mature B-cell DNA, pre-mRNA, and mRNA.
