Why are individual chromosomes not visible during interphase?
During interphase, the genetic material is called chromatin and can NOT be clearly seen because it isn’t tightly coiled. When prophase begins, the DNA molecules are progressively shortened and condensed by coiling, to form visible chromosomes.
Why is it difficult to observe individual chromosomes with a light microscope during interphase see?
Why is it difficult to observe individual chromosomes with a light microscope during interphase? They have uncoiled to form long, thin strands.
Why are the chromosomes not visible in most cells?
Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope. DNA and histone proteins are packaged into structures called chromosomes.
Why are individual chromosomes only visible during mitosis?
During most of the cell cycle, interphase, the chromosomes are somewhat less condensed and are not visible as individual objects under the light microscope. However during cell division, mitosis, the chromosomes become highly condensed and are then visible as dark distinct bodies within the nuclei of cells.
Can be the nucleus and nucleolus be seen during interphase?
In general, the nucleolus is visible only in interphase cells.
Why are individual chromosomes visible during mitosis?
What phase is the DNA most difficult to see under a microscope?
Interphase
The stage at which it is most difficult to see DNA is during Interphase.
What happens to the nucleus during interphase?
During interphase (1), chromatin is in its least condensed state and appears loosely distributed throughout the nucleus. Chromatin condensation begins during prophase (2) and chromosomes become visible. Chromosomes remain condensed throughout the various stages of mitosis (2-5).
Why are individual chromosomes visible only during mitosis quizlet?
Why are individual chromosomes visible only during mitosis? The fibers formed from nucleosomes packing together are dispersed in the nucleus during most of the cell cycle. They fold enormous lengths of DNA into the cell nucleus.
