one of two identical strands into which a chromosome splits during mitosis.
a strand which is formed by lengthwise division of a chromosome. Chromatids remain joined by the centromere until metaphase. At this stage the centromere divides, and the chromatids separate and become chromosomes.
One of two copies of a replicated chromosome during mitosis. Together they are called sister chromatids. Each one becomes a daughter chromosome at anaphase of mitosis and at the second meiotic division.
one of two copies formed by replication of the original chromosome. These physical copies remain attached at the centromere until anaphase of cell division.
one of a pair of identical connected nucleoprotein strands that are joined at the centromere and separate during cell division, each becoming a chromosome of one of the two daughter cells
a single strand of a chromosome; a replicated chromosome consists of two chromatids and an unreplicated chromosome consists of one chromatid
a daughter strand of a replicated chromosome. Replication of a chromosome produces two chromatids joined together at the centromere.
One copy of a duplicated chromosome, formed during the S phase of the cell cycle, that is still joined at the centromere to the other copy; also called sister chromatid. During mitosis, the two chromatids separate, each becoming a chromosome of one of the two daughter cells.
One copy of a chromosome formed by DNA replication that is still joined at the centromere to the other copy.
One of the two daughter strands of a duplicated chromosome.
homologous chromosomes joined to each other at the centromere; present during the prophase of mitosis.
The name given to the products of a chromosome that has divided during meiosis or mitosis, before separating off as separate daughter chromosomes. See also: chromosomal cross-over
One complete copy of a DNA strand and its associated nucleoproteins.
One of the two identical strands of chromatin (DNA plus associated proteins) that make up a chromosome in its duplicated state.
a single DNA molecule
One of the two strands of a chromosome; they are united by a centromere.
a pair of identical DNA molecules after replication joined together by centromeres, two chromatids make up one chromosome. chromatin = DNA/protein complex that makes up each chromosome
Single chromosome containing only one DNA duplex. Two daughter chromatids become visible at mitotic metaphase, though they are present throughout G2.
A single, continuous dsDNA molecule with its unique, complete grouping of genetic information, associated proteins, higher-order structures, and centromeric and telomeric regions necessary for separation and maintenance after replication.
One of the two side-by-side replicas produced by chromosome division.
One of a pair of duplicated chromosomes produced during the S phase of the cell cycle, which are joined together at the centromere.
Each of the two copies produced by chromosome replication, or each of the two DNA strands that comprise the chromosome.
Generally refers to a strand of a replicated chromosome; consists of DNA and protein. PICTURE
KRO-mah-tid A continuous strand of DNA comprising an unreplicated chromosome or one-half of a replicated chromosome. 171
A chromatid is one-half of a replicated chromosome.
One of the two identical strands of a newly replicated chromosome.
One of the pair of stands, formed by longitudinal splitting of a chromosome that are joined by a single centromere in somatic cells during mitosis; one of tetrad of strands formed by lengthwise splitting of paired chromosomes during the diplotene stage of meiosis.
Either of the two vertical halves of a chromosome that are joined at the centromere.
One of the two identical strands resulting from self-duplication of a chromosome during mitosis or meiosis.
Each of the two daughter strands of a duplicated chromosome joined at the centromere during mitosis and meiosis
one half of a replicated chromosome which is joined to the other half at the centromere.
A single molecule of DNA and associated proteins found as part of a duplicated(replicated) chromosome.
During cell division each chromosome divides longitudinally into two strands, or chromatids, which are held together by the centromere.
One of the usually paired and parallel strands of a duplicated chromosome joined by a single centromere.
A chromatid is one of two identical strands of DNA making up a chromosome that are joined at their centromeres, for the process of nuclear division (mitosis or meiosis). The term is used so long as the centromeres remain in contact. When they separate (during anaphase of mitosis and anaphase 2 of meiosis), the strands are called daughter-chromosomes.The tips of the chromatid are called telomeres.They are there to prevent the ends of the chromosome from attaching to other chromosomes.
