Why are chromosome called doubled chromosomes just before mitosis begins?
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
Cell division and chromosome duplication?
Cell division is the process by which a cell divides into two daughter cells. Chromosome duplication occurs during the cell cycle when the DNA is replicated to create identical copies of each chromosome. This ensures that each daughter cell receives a complete set of genetic material.
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
Each chromosome consists of 2 what?
Each chromosome consists of two sister chromatids, which are identical copies of the chromosome connected at a region called the centromere. During cell division, the sister chromatids separate and each is passed on to a daughter cell.
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.
The two copies of DNA on each chromosome that form just before cell division?
Chromatids

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.

Each chromosome consists of 2 what?
Each chromosome consists of two sister chromatids, which are identical copies of the chromosome connected at a region called the centromere. During cell division, the sister chromatids separate and each is passed on to a daughter cell.
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.
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.
How is the chromosome number halved during cell division: mitosis or meiosis?
The chromosome number is halved during cell division in meiosis, not mitosis.
What is a Cell that has two copies of each chromosone called?
A cell that has two copies of each chromosome is called a diploid cell. This means that each chromosome in the cell has a matching homologous chromosome. Humans have diploid cells in their body, with a total of 46 chromosomes arranged in 23 pairs.
Type of mutation that causes Trisomy 18?
Trisomy 18 is caused by a type of mutation called nondisjunction, where an error in cell division results in an extra copy of chromosome 18. This leads to the presence of three copies of chromosome 18 in each cell instead of the normal two copies.
