Prokaryotic chromosomes are less condensed than their eukaryotic counterparts and don’t have easily identified features when viewed under a light microscope. Figure 2: A the appearance of DNA during interphase versus mitosis. During interphase, the cell’s DNA is not condensed and is loosely distributed.
What is it called when your DNA is uncoiled and not condensed?
During this phase, the DNA is uncoiled and called chromatin.
What do you think might happen if the chromosomes were not condensed?
Eukaryotic cells must sort their chromosomes during mitosis so each daughter cell receives the correct number of chromosomes. … What do you think might happen if the chromosomes were not condensed? To produce identical quadruplets, fertilization begins with one sperm and one egg cell.
What would happen if DNA was not condensed?
During mitosis, the chromosomes condense so that each chromosome is a distinct unit. Prior to mitosis, the cell copies its DNA so that it contains two copies of each chromosome. … If the chromosomes do not line up properly, severe genetic abnormalities can occur, which can lead to death of the cell or cancer.
What can happen if cells do not duplicate correctly?
Answer: If the cell has not properly copied its chromosomes, an enzyme called cyclin dependent kinase, or CDK, will not activate the cyclin, and the cell cycle will not proceed to the next phase. The cell will undergo cell death.
Is chromosome condensation reversible?
In late anaphase and telophase the mitotic chromatin decondenses to re-establish its interphase structure (Figure 3). Decondensation is not a simple reversal of events leading to condensation.
Why is chromosome condensation important?
Chromosome condensation is mediated by the condensin complex, among other proteins, and is necessary to prevent chromosomes from being entangled during chromosome segregation.
When the cell’s DNA is condensed it is called?
Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. Nuclear DNA does not appear in free linear strands; it is highly condensed and wrapped around nuclear proteins in order to fit inside the nucleus. Chromatin exists in two forms.
