Centromere - Wikipedia The 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 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 cell’s DNA
Centromere - National Human Genome Research Institute The centromere appears as a constricted region of a chromosome and plays a key role in helping the cell divide up its DNA during division (mitosis and meiosis) Specifically, it is the region where the cell’s spindle fibers attach
Centromere | chromosome, DNA, replication | Britannica Centromere, 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 the mitotic spindle become anchored
Centromere Structure and Function - PMC - PubMed Central (PMC) The centromere is the genetic locus that specifies the site of kinetochore assembly, where the chromosome will attach to the kinetochore microtubule The pericentromere is the physical region responsible for the geometry of bi-oriented sister kinetochores in metaphase
Centromere - Definition and Examples - Biology Online Dictionary A centromere is the dense and constricted region of a chromosome It is where the sister chromatids attach after DNA replication and kinetochore assembly (for spindle fiber attachment) take place before mitosis It contains highly specialized repetitive DNA sequences (e g satellite DNA) of a chromosome linking sister chromatids forming a dyad
What is a Centromere? (with pictures) - AllTheScience Each chromatid contains a copy of the replicated DNA and the area where the chromatids are held together is called the centromere Centromeres can be found anywhere along the length of the chromosome, but the position is specific for each particular chromosome
