For this reason, human peripheral blood lymphocytes were treated with varying concentrations of EMS (5×10-4M, 10-3M and 2×10-3M) for 24 and 48 hours. The percentages of chromosomal fragmentations in EMS-treated and untreated (control) cells were found to be statistically significant. In addition, the extent of breakages of the same chromosomes correlated with the concentrations of the chemical. The chromosomes that were fragmented most as a result of EMS-treatment in descending order were 1, 2, 6, 4, X, 7, 3, 5, 9, and 8.trinfo:eu-repo/semantics/closedAccessChromosome damageEthyl methanesulfonate (EMS)Human lymphocytesLymphocyte cultureArticle45511452932534
