Chromatin is DNA wrapped around a sequence of histone proteins (nucleosomes) to allow full strands of DNA to fit inside the nucleus. At the beginning of cell division the histone proteins condense and join together to form a chromatid, a copy package of DNA also known as a 30 nm fiber.
Sometimes one chromatid is present in a chromosone however prior to cell division this copy of DNA is duplicated to create a chromosone with two chromatids.
Hi,
Basically, a chromosome is two chromatids joined together at the centromere, and the two chromatids on a chromosome are identical. Normally, the cell only needs one copy of each set of genetic material so chromatids are enough, but because the genetic information of the cell will be distributed to two daughter cells during mitosis/meiosis the chromatids must be doubled. This is achieved in the S-Phase of a cell cycle. With two copies of each allele, the genetic information will be evenly distributed and will be the same between the two sister cells.
Hope this helps
What else can I help you with?
What is different between a chromosome and a chromatid?
Chromosome need 2 chromatids but a chromatid is only half of a chromosome
In a chromosome pair connected by a centromere what is each individual chromosome called?
chromatid
How are chromatid and a duplicated chromosome are related?
Chromosomes and chromatids are related in that one is the duplicate of another. A chromatid comes about when chromosomes are duplicated. It holds replicated DNA of every single chromosome that is joined.
What is a chromosome called after it trplicates and divides?
A chromatid.
What is it called when two chromosomes exchange parts?
mutagenesis occurs
When a chromosome has made a copy of itself each of the two strands is called this?
When a chromosome has made a copy of itself, each of the two strands is called a sister chromatid. Sister chromatids are identical copies formed during DNA replication and are joined at the centromere.
How do you use chromatid in a sentence?
chromatid is a individal strand in a chromosome.....
The two chromatid arms on a chromosome are what?
The two chromatid arms on a chromosome are known as sister chromatids, which are genetically identical copies created during DNA replication. Sister chromatids are joined at the centromere and are separated during cell division.
What is a single arm of a chromosome called?
A single arm of a chromosome is called a chromatid. During cell division, each chromosome consists of two sister chromatids that are joined together at a region called the centromere.
Compare chromosome and chromatid?
chromosomes are made of 2 chromatids
The two chromatid arms on a chromosome are?
Complementary to each other
What can one half of a duplicated chromosome be referred as?
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.Joined chromatids are known as sister chromatids. Once the joined sister chromatids separate from one another in anaphase of mitosis, each is known as a daughter chromosome.Chromatids are formed from chromatin fibers.Bailey, Regina. "Chromatid."
