How the chromosomes move during anaphase
NettetHomologous chromosomes a) are formed when the chromosomes separated during anaphase b) are a set of chromosomes that a cell receives from one parent are only present as chromatin d) carry the same genes in the same sequence e) do not include the sex chromosomes. BIOLOGY:CONCEPTS+APPL. NettetIt consists of two distinct processes: Anaphase A, the movement of chromosomes toward spindle poles via shortening of the connecting fibers, and anaphase B, …

Nettet8. des. 2024 · The correct answer is d. During anaphase, the sister chromatids begin to separate by moving to the opposite poles. This movement is facilitated by the … Nettet13. apr. 2024 · During microgenesis, both the movement of homologous or sister chromosomes and postmeiotic cytokinesis are closely related to dynamic changes in the organization of microtubules [46,47]. In diploid Populus species, the misorientation of spindle microtubules and the failure of postmeiotic cytokinesis have been attributed to …
Nettetmoves the chromosomes to the poles of the spindle; and secondly, the elongation of the spindle body, which further separates the chromosomes. In the Homoptera and … NettetDuring anaphase, sister chromatids separate and move to the spindle poles (Figures 2 and 3). Anaphase consists of two phases, anaphase A and B. During anaphase A, the chromosomes move to the poles and kinetochore fiber microtubules shorten; during anaphase B, the spindle poles move apart as interpolar microtubules elongate and …
