Dec 30, 2022 · Figure 16.9.19 16.9. 19. DNA rearrangement of a k light chain gene. (A) The germline DNA has approximately 40 V region genes, 5 J segments, and one C region gene. (B) By action of the V (D)J recombinase, a random V region is brought close to a random J region, and the intervening sequence is cut out (C).
Oct 31, 2023 · Figure 13.2B. 1 13.2 B. 1: Inversion heterozygotes: When one chromosome undergoes an inversion, but the other does not, one chromosome must form an inverted loop to retain point-for-point interaction during synapsis. This inversion pairing is essential to maintaining gene alignment during meiosis and to allow for recombination.
Like other programmed gene rearrangements, however, gene amplification is a relatively infrequent event that occurs in highly specialized cell types; it is not a common mechanism of gene regulation. Gene amplification also occurs as an abnormal event in cancer cells, where it results in the increased expression of genes that contribute to uncontrolled cell growth.
