WebSep 28, 2010 · An inversion occurs when a chromosome breaks at two points and the segment bounded by the breakpoints is reinserted in the reversed orientation. Several molecular mechanisms can mediate this event [4]. Box 1 gives an overview of some basic properties of inversions and the ways that they are detected. Box 1. WebYeast cells have a haploid chromosome number of 16. A haploid cell disomic for two different chromosomes has the same chromosome number as a: A. a haploid cell tetrasomic for one chromosome B. a triploid cell C. a diploid cell that is monosomic for two different chromosomes D. a diploid cell E. a haploid cell trisomic for one chromosome K40.
WebChromosome 16 inversion is one of the most common chromosome abnormalities in human acute myeloid leukemia.
