Multiple Choice

You are studying a weasel and find that its genome contains 7 J $\kappa$ and 55 V $\kappa$ genes.Other sources of variation like changes in the site at which a J sequence joins a V sequence and the ability of deoxynucleotidyl transferase to insert nucleotides at sites of strand breakage have been found to introduce an additional ten-fold increase in variability.Assuming that any V sequence can join with any J sequence,how many different $\kappa$ chains can this organism make?

• A)620
• B)385
• C)3850
• D)70
• E)550
