Yes, chromatids form when DNA replicates prior to cell division. During the S phase of the cell cycle, each chromosome is duplicated, resulting in two identical copies called sister chromatids. These chromatids are connected at a region known as the centromere until they are separated during cell division. This process ensures that each daughter cell receives an identical set of chromosomes.

What happens to a cell's DNA prior to cell division?
It replicates.
What happens to the DNA in your cells prior to cell division?
Cell division is a process in which a cell divides (roughly equally) to give two daughter cells. Therefore, there have to be two copies of the genome even before mitosis begins. When we look at the cell cycle, there are four distinct phases: G1, S, G2 and M. The S phase is where the DNA replicates. Once there are two copies in the genome, the cell goes through the G2 phase and then enters the M (mitosis) phase.
What period of meiosis in which the cell replicates its chromosomes?
The period of meiosis in which the cell replicates its chromosomes is called interphase, specifically during the S phase (synthesis phase) of the cell cycle. This occurs before meiosis begins and ensures that each homologous chromosome has been duplicated, resulting in sister chromatids. Following interphase, meiosis proceeds with two rounds of division: meiosis I and meiosis II.
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 phase does preparation for cell division occur?
during interphase the cells prepare for the divsion and the DNA replicates and chromosomes form
Prior to cell division each chromosome replicates it genetic material The products are connected by a centromere and are called?
The products are called sister chromatids. Sister chromatids are genetically identical and connected at the centromere, which holds them together until they are separated during cell division.
What happens to a cell's DNA prior to cell division?
It replicates.
How many chromatids in a cell in which DNA synthesis has occurred prior to cell division?
58 chromatids
How are sister chromatids formed during the process of cell division?
During cell division, sister chromatids are formed when a single chromosome replicates to create two identical copies. These copies are held together at a region called the centromere, resulting in the formation of sister chromatids.
Why are there two chromotids?
There are two chromatids for each chromosome during the cell division process because, prior to mitosis or meiosis, the DNA replicates. This replication results in two identical copies, called sister chromatids, which are joined at a region called the centromere. The presence of two chromatids ensures that each daughter cell receives an identical set of chromosomes during cell division. This is crucial for maintaining genetic consistency across generations of cells.
Why are there two chromatids of each color what must have happened to each chromosome prior to mitosis?
During interphase before mitosis, each chromosome replicates to form two identical sister chromatids. This ensures that each daughter cell receives a complete set of genetic information during cell division.
During cell division each single long strand of DNA becomes fully condensed in the form of a?
During interphase, DNA replicates and becomes fully condensed in the form of sister chromatids. When the sister chromatids separate, they will each be called a chromosome.
How are sister chromatids joined at the centromere during cell division?
During cell division, sister chromatids are joined at the centromere by protein complexes called cohesins. These cohesins hold the sister chromatids together until they are separated during the later stages of cell division.
The number of sister chromatids in a human body cell that is entering cell division is?
The number of sister chromatids in a human body cell entering cell division is twice the haploid number, as each chromosome is replicated and consists of two sister chromatids held together by a centromere. This means that there are 46 pairs of sister chromatids in a normal human body cell entering cell division.
