What phase does chromosomes first appear to be double?
It is during the prophase in which chromosomes first appear to be duplex structures.Each cell in a person typically has 23 pairs of chromosomes.
Why is it necessary for chromatin to condense into tightly packed chromosomes?
DNA does not condense into chromosomes. When cells divide so do chromosomes. Each chromosome provides the template for a new chromosome. The four bases match those on the old chromosomes and create new chromosomes. DNA does not just decide to get together, "Hey guys, lets get together and become a chromosome." ACTUALLY they do condense into chromosomes because it would be too big (if uncoiled and stretched out) to fit into a cell
Why do chromosomes become more visible during prophase?
Because the chromosomes seem to shorten and thicken prior to dividing, this makes them more visible.
Why do the chromosomes become easier to see under the microscope just before mitosis?
during mitosis and meiosis because the condensed chromosomes are thicker and therefore more prominent.
The chromosomes become invisible?
The stages of mitosis are: Interphase Preprophase Prophase Prometaphase Metaphase Anaphase Telophase Cytokinesis The Chromosome condense and become visible during prophase.
Does condensing a liquid change it to a gas?
No.Gases condense ("become thicker") to form liquids.Liquids evaporate to become gases.
Describe the chromosome during prophase stage?
During prophase, the chromatin in the nucleus begins to condense to form chromosomes. Nuclear envelope and nucleolus dissolves. In meiosis, during early and middle prophase I of meiosis the chromosomes become distinct and rodlike. Also during early and middle prophase I of meiosis synapsis occurs. During late prophase I of meiosis the chromosomes become clearly double-stranded and the nuclear membrane begins to disappear.
Is it possible to distinguish individual chromosomes after telophase?
No, after telophase (a.k.a. during interphase) the chromosomes entangle as they replicate however it does again become possible for individual chromosomes to be distinguished in prophase as the chromosomes begin to 'coil up' or condense.

What are the 8 steps of?
Prophase I: chromosomes start to condense and become visibleMetaphase I: homologous chromosomes line up at equatorial plateAnaphase I: homologous chromosomes separate and move to diferent polesTelophase I: one set of chromosomes arrive at each poleProphase II: chromosomes condense againMetaphase II: individual chromosome line up at equatorial plateAnaphase II: centromere divides, and chromosomes (from chromatids) move to different polesTelophase II: one set of chromosome arrive at each pole.
Chromosomes first become visible during which phase of mitosis?
Chromosomes first become visible during prophase of mitosis when they condense and coil up tightly. This allows them to be easily seen under a microscope as separate structures.
Do chromosomes become visible and short?
Yes, chromosomes become visible and appear shorter during the process of cell division. This is because they condense and coil up tightly in order to be more manageable during cell division. As a result, they become visible under a microscope as distinct structures.
The chromosomes become invisible?
The stages of mitosis are: Interphase Preprophase Prophase Prometaphase Metaphase Anaphase Telophase Cytokinesis The Chromosome condense and become visible during prophase.
In what phase does chromosomes condense and become visible?
The chromosomes in a cell's nucleus are only visible during the part of the cell cycle known as prophase. Prophase is the stage of mitosis in which chromatin condensation occurs.
