Dicentric chromosome - Wikipedia

A dicentric chromosome is an abnormal chromosome with two centromeres. It is formed through the fusion of two chromosome segments, each with a centromere, resulting in the loss of acentric fragments (lacking a centromere) and the formation of dicentric fragments. The formation of dicentric chromosomes has been attributed to genetic processes, such as Robertsonian translocation and paracentric inversion. Dicentric chromosomes have important roles in the mitoti… WebThe peripheral blood karyotype was 46,XX,r (13) (p11q33) [82]/45,XX,-13 [10]/46,XX,r (13;13) (p11q33;p11q33) [8], and array-based comparative genomic hybridization … ipsea local offer https://enlowconsulting.com
