The immunoglobulin light chain does not have a d segment. in humans, there are two different possible light chain proteins, termed kappa and lambda. assume that there are 35 v segments and 5 j segments in the human kappa light chain region, and there are 30 v segments and 4 j segments in the human lambda light chain region. how many possible light chain genes can be created from these different segments, simply due to combinatorial diversity? enter an exact number.

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
