What phase is occurring when chromatids are separate and a visible line forms between sets of chromatid?
The phase occurring when chromatids are separated and a visible line forms between sets of chromatids is called anaphase. During anaphase, the sister chromatids are pulled apart toward opposite poles of the cell by the spindle fibers. This separation ensures that each new daughter cell will receive an identical set of chromosomes during cell division. The formation of the visible line indicates the cleavage furrow beginning to form as the cell prepares for cytokinesis.

What are segments of nonsister chromatids that break and reattach to the other chromatid?
Segments of nonsister chromatids that break and reattach to the other chromatid are known as crossover events. During meiosis, crossover events occur during prophase I and involve the exchange of genetic material between homologous chromosomes, increasing genetic diversity in offspring.
What is the difference between a chromatid and a sister chromatid?
Homologous chromosomes is a pair made of a paternal and maternal chromosomes. But sister chromatid is either pairs of paternal or maternal chromosomes
What is the relationship between chromaids and chromosomes?
Normally a cells chromosomes are single strands - a bit like a pice of string. Just prior to cell division, a chromosome replicates (=makes another copy of itself) and these two copies are joined together at a point called the centromere. Each copy is now called a chromatid and being joined at the centromere make the familiar "X" shape, with each copy (chromatid) forming a side of the X and will have exactly the same sequence of genes down its length as the other chromatid (they are copies!). In cell division the copies (chromatids) will be pulled apart (X becomes > <) to become chromosomes in their own right.
What is the difference between a chromatid and a centromere?
The centromere is the region of the chromosome that holds the two sister chromatids together during mitosis. The chromatid is one of the two strands of chromosomes that become visible during mitosis or meiosis.
What is the relationship between chromatin and chromatid?
chromosomes are the things you inherited from your parents. 23 pairs. 46 total. (like 23 pairs of socks) chromatids are the individual chromosomes in a pair (so like having two red socks, two blue socks. one red sock is a sister chromatid to the other red sock, and same with the two blue socks.) chromatin is the strands of DNA combined with proteins that make up the chromosome (the thread used to make the socks) BY-Arindam Jain IX-A
What is different between a chromosome and a chromatid?
Chromosome need 2 chromatids but a chromatid is only half of a chromosome
Are the genes on a recombinant chromatid the same as the original chromatid?
No, the genes on a recombinant chromatid are a combination of genes from the original chromatids. During crossing over in meiosis, genetic material is exchanged between homologous chromosomes, resulting in a new combination of genes on the recombinant chromatid.
What are segments of nonsister chromatids that break and reattach to the other chromatid?
Segments of nonsister chromatids that break and reattach to the other chromatid are known as crossover events. During meiosis, crossover events occur during prophase I and involve the exchange of genetic material between homologous chromosomes, increasing genetic diversity in offspring.
What is difference between chromosome and chromatids?
A chromatid is one-half of two identical copies of a replicated chromosome. During cell division, the identical copies are joined together at the region of the chromosome called the centromere. They are known as sister chromatids. Once the paired sister chromatids separate from one another in anaphase of mitosis, each is known as a daughter chromosome.

If one arm of a chromatid crosses over the arm of another chromatid what results?
A DNA exchange called crossing over occurs, leading to genetic recombination between the chromatids. This increases genetic variability by mixing genetic material between homologous chromosomes during meiosis.
What is the difference between a chromatid and a sister chromatid?
Homologous chromosomes is a pair made of a paternal and maternal chromosomes. But sister chromatid is either pairs of paternal or maternal chromosomes

How are DNA centrimere chromosomes chromatid and chromatin are related?
Chromatid- one of two identical parts of the chromosome after "S" phaseCentromere- the point where the two chromatids crossChromosome- carries DNA in (and between) organisms.

Holds sister chromatids together?
The primary structure that holds sister chromatids together is the centromere. This region of DNA is responsible for ensuring that each daughter cell receives one copy of each chromatid during cell division. Additionally, proteins known as cohesins also play a role in maintaining the physical connection between sister chromatids until they are separated during mitosis or meiosis.
