WebChromosome breakage study performed by culturing cells in both Mitomycin-C (MMC) and Diepoxybutane (DEB). These studies involve culturing of living cells; therefore, turnaround times given represent average times, which are subject to multiple variables. WebChromosomal structural abnormalities are the result of chromosome breakage followed by anomalous reconstitution. Rearrangements result spontaneously or are due to inducing agents, such as ionizing radiation. Structural abnormalities can be divided into two categories—balanced and unbalanced.
