Chromatids in Biological Definition

Anaphase

... , by the end of which fully condensed sister chromatids are arranged in pairs, their centromeres lying ... , the protein responsible for holding sister chromatids together. They immediately separate, marking the ... distinct processes occur. During anaphase A the chromatids abruptly separate and move towards the spindle ...

Chromosome

... phase . (2) Centromere . The point where the two chromatids touch, and where the microtubules attach. (3) ... transport form. Eventually, the two matching chromatids (condensed chromatin strands) become visible as ... cell. During mitosis, the microtubules pull the chromatids apart, so that each daughter cell inherits one ...

Genetic recombination

... chromosomal replication , the four available chromatids are in tight formation with one another. During this time, homologous sites on two chromatids can mesh with one another, and may exchange ... chromatids; after crossing over, each of the four chromatids carries a unique set of genetic information. ...

Chromatid

... chromatids. After they have been pulled apart by the mitotic spindle , chromatids are called "chromosomes". Sister chromatids are joined at a point called the centromere . In non-gametic, ...

Meiosis

... of spindles and spindle fibres as well as the uncoiling of the chromatids and the reformation of the nuclear membrane. Pinching of the cytoplasm or ... II , where the centromeres divide and the fibres pull the now separated chromatids (i.e. chromosomes) are pulled behind the centromere. The process ends ...

Mitosis

... is called a chromosome. Just to be even more confusing, when the chromatids separate, they are no longer called chromatids, but are called chromosomes ... This is divided into two phases. First, the proteins that bind the sister chromatids together are cloven, allowing them to separate. They are pulled apart by ...

Mitotic spindle

... center of the spindle. Once all the chromosomes are aligned with sister chromatids pointing to opposite ends of the spindle, the sister chromatids separate and are dragged away from each other, ensuring that each ...

Mitosis

... is called a chromosome. Just to be even more confusing, when the chromatids separate, they are no longer called chromatids, but are called chromosomes ... This is divided into two phases. First, the proteins that bind the sister chromatids together are cloven, allowing them to separate. They are pulled apart by ...

Prophase

... individual chromosome in the pair is called a chromatid , while the whole unit (confusingly) is called a chromosome. Somewhat confusingly, when the chromatids separate, they are no longer called chromatids, but are called chromosomes again. The task of mitosis is to assure that one copy of each sister ...
