When chromosomes become visible at the beginning of cell division what does each chromosome consist of?
The consist of DNA and various HistonesIn eukaryotes,genetic information is passed on by chromosomes. Well before cell division, each chromosome is replicated(copied). When copying occurs, each chromosome consists of two identical ''sister''chromatids.
What phase of the cell cycle duplicates chromosomes before division?
The phase of the cell cycle that duplicates chromosomes before division is called the S phase.
During cell life when do chromosomes duplicate?
Chromosomes duplicate during the S phase of the cell cycle, which occurs after DNA is replicated and before cell division (mitosis or meiosis). This ensures that each daughter cell receives a complete set of chromosomes with identical genetic material.
In a human nucleus just before cell division how many chromatids are present?
Normally in a cell, there are 92 chromatids, 2 per chromosome. However, when the chromosomes have duplicated before mitosis, there are twice as many, or 184.
The period in which chromosomes duplicate?
Chromosomes duplicate during the S phase of the cell cycle, which occurs after the G1 phase and before the G2 phase. In this phase, DNA replication takes place to create identical sister chromatids that will eventually be separated during cell division.

Which cell division mitosis or meiosis has genetic variation and are not just identical cells?
Meiosis. Genetic variation is achieved by the random division of the chromosomes between the two daughter cells, and further recombination of specific genes between paired chromosomes before the division.
What is the genetic material contained in each of the 46 chromosomes of a human cell just before division?
The genetic material in each of the 46 chromosomes of a human cell just before division is DNA. DNA carries the instructions for building and maintaining an organism. During cell division, the DNA is replicated and then divided equally between the new cells.
Why are chromosomes called double chromosomes before mitosis?
Just before cell division begins,the amount of DNA doubles and so do the chromosomes.Each doubled chromosome consists of two copies of the original chromosome joined at the center
How many chromosomes does a human cell have before division?
64 chromosomes
What division is sexual?
It is a division that reduces the number of chromosomes to half of their number before the division.
What phase of the cell cycle duplicates chromosomes before division?
The phase of the cell cycle that duplicates chromosomes before division is called the S phase.
A duplicated chromosome consists of two?
Two sister-chromatids.Each chromatid consists of a molecule of DNA together with associated proteins. There are two DNA molecules (sister-chromatids) following the replication of DNA midway through the preceding interphase. The sister-chromatids are therefore genetically identical.chromatidschromatidsThe two identical joined chromosomes before cell division begins is called sister chromatids.

Why must chromosomes double before mitosis?
Just before cell division begins,the amount of DNA doubles and so do the chromosomes.Each doubled chromosome consists of two copies of the original chromosome joined at the center
What occurs in mitosis that gives the new cell identical DNA?
There are several things that occur in mitosis that gives the new cell identical DNA. The chromosomes have to be doubled first and then division of the nucleus takes place to make new identical cells.
