Centromere - Wikipedia
WebThe centromere links a pair of sister chromatids together during cell division. This constricted region of chromosome connects the sister chromatids, creating a short arm (p) and a long arm (q) on the chromatids.
Centromere - Definition, Function and Types | Biology Dictionary
WebApr 28, 2017 · Centromere Definition. The centromere is the point on a chromosome where mitotic spindle fibers attach to pull sister chromatids apart during cell division. When a cell seeks to reproduce itself, it must first make a complete copy of each of its chromosomes, to ensure that their daughter cell receives a full complement of the parent …
The variation and evolution of complete human centromeres
WebApr 3, 2024 · Human centromeres have been traditionally very difficult to sequence and assemble owing to their repetitive nature and large size 1. As a result, patterns of human centromeric variation and...

WebCentromere, structure in a chromosome that holds together the two chromatids (the daughter strands of a replicated chromosome). The centromere is the point of attachment of the kinetochore, a structure to which the microtubules of …
Chromosome Segregation in Mitosis: The Role of Centromeres
WebThe primary function of the centromere is to provide the foundation for assembly of the kinetochore, which is a protein complex essential to proper chromosomal segregation during mitosis.

WebNov 25, 2015 · The centromere is the region of the chromosome that directs its segregation in mitosis and meiosis. Although the functional importance of the centromere has been appreciated for more than 130...
Centromere - an overview | ScienceDirect Topics
WebThe centromere is the chromosome region that attaches to a spindle fibre at metaphase of mitosis or meiosis and moves to the spindle pole at anaphase, pulling the rest of the chromosome behind it.
Centromere - an overview | ScienceDirect Topics
WebAll centromeres are associated with the centromere-specific histone CENP-A. CENP-A is required to recruit all other centromere and kinetochore proteins, with the exception of HP1, making it is a strong candidate for a protein that specifies and maintains the site of kinetochore assembly.
