Even if DNA duplicates the chromosomes do not necessarily duplicate?
During DNA replication, the entire DNA molecule is duplicated, which includes the chromosomes. However, chromosomes only become visible as distinct structures during cell division, when they condense and organize into a compact form. Outside of cell division, chromosomes exist in a less condensed state called chromatin, which allows the DNA to be accessible for gene expression and other cellular processes. So, while DNA replication leads to chromosome duplication, the chromosomes themselves may not appear as distinct entities outside of cell division.
What happens to cell membrane as cell divides?
No, the nucleus in a cell is what controls cell division.
How the chromosomal number of the cell is kept constant through mitosis?
By uniform replication of DNA and division of centomeres, the daughter nuclei receive the same number of chromosomes.
The cell structure that helps move chromosomes along in an organized manner during cell division is?
spindle
What form a spindle shape structure of protein fibres on which the chromosomes move durung nuclear division?
Centrosomes
Is the process of duplicating chromosomes prior to cell division.?
DNA replication
What is it called when DNA separate into two strands?
DNA Replication by enzymes that copy DNA for chromosomes in the new cell after cell division (mitosis)
Does DNA replication occur after telophase 1?
Telophase is a phase of mitosis. DNA replication must occur before mitosis begins. If it does not then the DNA chromosomes may not be consistent throughout the division of the cells.
What chromosomes are affected by colon cancer?
Well, Cancer is when abnormal cells divide out of control. The chromosomes are the DNA that controls Cell Division
Why does chromatin condense to form chromosomes?
Cells condense their chromatin into chromosomes only when cell division is occurring

What are chromosomes and genes composed of?
Genes are composed of DNA. Chromosomes are composed of DNA and proteins. Genes are the sections of DNA which code for a functional product (such as a protein). Chromosomes are the compact, tightly-coiled form of DNA. These appear before the cell undergoes division/replication.
What 2 cell division processes use DNA replication?
Two types of cell division in eukaryotes (nucleated organisms) are meiosis and mitosis. Meiosis halves the number of chromosomes and produces gametes. Mitosis retains the number of chromosomes and is involved in growth and repair of injury.
