Definitions from the WebAcentric ChromosomeDescription:An acentric chromosome refers to a chromosome lacking a centromere, a specialized region that plays a crucial role in cell division. Acentric chromosomes may arise from chromosome breakage or as a result of errors during chromosome replication. Senses:1. Genetics:In genetics, an acentric chromosome lacks a functional centromere, which impedes its proper segregation during cell division. Acentric chromosomes are often unable to align correctly with other chromosomes during meiosis, leading to genetic disorders or cell death. Example Sentence:An individual carrying an acentric chromosome may experience fertility issues due to improper segregation during gamete formation. 2. Cytogenetics:In the field of cytogenetics, an acentric chromosome is characterized by the absence of a centromere, resulting in an atypical chromosome structure. These aberrant chromosomes can be visualized using various staining techniques and microscopy. Example Sentence:The presence of acentric chromosomes in a karyotype analysis suggests the occurrence of chromosomal rearrangements or genomic instability. Related Products: | ||||
