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 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 are the differences between chromatin and chromosomes?
Chromatin and chromosomes are basically the same thing. The difference is that chromatin is unfolded, uncondensed, extended DNA while chromosomes are condensed DNA. Chromosomes are condensed chromatin and chromatin is unfolded chromosomes. The only difference I know is that chromatin are present normally in a cell, while chromosomes are there only when the cell is about to divide. When the cell is about to divide, the chromatin threads get organised into chromosomes. Utilizing their histone proteins to accomplish this, DNA first condenses into 10 nm strands and then into 30 nm strands, ready for Condensation and then Cytokinesis.
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 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 different between a chromosome and a chromatid?
Chromosome need 2 chromatids but a chromatid is only half of a chromosome
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.

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.
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 difference between sister and non sister chromatids?
Sister chromatids are those replicated from the same chromosome whereas non-sister chromatids may be found in meiosis (particularly metaphase II) where paternal and maternal chromatids line up and eventually separate at the metaphase plate.

What is difference between a chromosome and a chromatid?
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 is the difference between recombinant and parental chromatids and how do they arise?
Parental chromatids are chromatids that have a combination of alleles identical to the parents and Recombinant chromatids are chromatids that have a mix of alleles from both parents.

What occurs in meiosis but not in mitosis?
The crossing over of the chromosomes.Synapsis of Homologous chromosomes does not occur in Mitosis.In Meiosis, occurs during Prophase I along with crossing over between non sister chromatids; resulting chiasmata hold pairs together due to sister chromatid cohesion.
What is the point of attachment between two chromatids?
The point of attatchment between two chromatids is called the centromere. When two chromatids are connected, it is called a chromosome which is essential in DNA replication, or, mitosis.
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.
