[英文釋義] Genes encoding the light and heavy chain segments of immunoglobulins. Light chain gene segments are symbolized L-V (variable),J (joining) and C (constant); Ig heavy chain segments have,in addition,a diversity (D) gene. Each segment codes for certain amino acids,and each has a different nucleotide sequence; the genes are assembled by a remarkable shuffling of the segments during B lymphocyte maturation.
