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 phase does preparation for cell division occur?
during interphase the cells prepare for the divsion and the DNA replicates and chromosomes form
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.
During cell division this shortens to pull the chromatids apart.?
spindle fibers
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 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.
