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.

∙ 12y agoA centromere is a cellular structure involved in meiosis that creates spindle fibers and allows chromosomes to separate in cells. Telomeres are single-stranded DNA tails that form at the end of replicated DNA strands because they cannot be replicated. They are nonsense DNA, so nothing is lost in not replicating them. They protect exons--expressed DNA segments, and work in the cell aging process.

What is the difference between kinetochore and centromere?
kinetochore is the site of attachment of spindlefibres. centromere is the center of attachment of the chromatids
What is a chromosome has been duplicated the two indentical portions that are attached by their centromere?
Sister Chromatids
What is a list of the 3 parts of a chromosome?
Telomere - The ends of the chromosome. Centromere - The primary constriction of the chromosome. Chromatid - A single molecule of DNA. The centromere also divides the chromosome into a short arm (p) and a long arm (q).
What is a disk protein at the centromere region of the chromatid that serves as a platform for assembling microtubules?
When a chromosome has replicated and is preparing for division, the two chromatids are connected by the centromere. The centromere is the site where the kinetochore forms. The kinetochore forms the attachment with the spindle fibers.
What is the sides of a chromosome called after they are in the structure?
each side of the chromosome is called a chromatid they are bonded together by the centromere
The chromatid is attached to a spindle fiber by what?
one word Centromere
How many sister chromatids are there in a duplicated chromosomes?
2. A chromatid is basically a chromosome - its just connected to another chromatid via a centromere.
In a chromosome pair connected by a centromere what is each individual chromosome called?
chromatid
What is the difference between kinetochore and centromere?
kinetochore is the site of attachment of spindlefibres. centromere is the center of attachment of the chromatids

Difference between paracentric and pericentric inversion?
The position of the centromere in the recombinant products.
A c..... is made up of two c..... arms joined in the middle by a c....?
chromosome, made up of chromatid arms, joined by centromere.
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.
