What is the phase where chromation condenses form to chromosomes?
The cell's chromatin condenses into chromosomes during prophase. In contrast, telophase is where the chromosomes loosen to form chromatins.
Are dyads visible during mitosis?
Yes, with a microscope. During mitosis, the chromatins condense to form chromosomes, which are visible under a microscope.
Why do chromosomes become more condensed during cell reprouction?
Chromatins are coiled to form chromosomes, which gives a thicker, more condensed look.
What are two types of chromosomes in the body how are they different?
the two types of chromatins are euchromatin and heterochromatin.They are different in that heterochromatin is coiled while euchromatin is not coiled.It is this coiling that makes heterochromatin inactive and therefore less in the nucleus when the nucleus is actively involved in protein synthesis.On the other hand,euchromatin is active because its DNA is exposed. When viewed under a microscope,the two chromatins have different stains.
Why cant you see the chromosomes during interphase?
In interphase, the DNA has just replicated and exists as loosely coiled chromatins. They have not yet condensed enough to be the form of a chromosome. In the next stage, prophase, the DNA will shorten and condense into the easily recognizable chromosome structure.
What is the relationship between chromatin and chromosomes?
chromatin is the diffuse form chromosomes take in the nucleus of a cell when it is not dividing.
What is the phase where chromation condenses form to chromosomes?
The cell's chromatin condenses into chromosomes during prophase. In contrast, telophase is where the chromosomes loosen to form chromatins.
What do you call DNA in the nucleus before it condenses to form chromosomes?
DNA forms nucleosomes (beads on the string) by combining histone proteins, nucleosomes condense into chromatins before it forms Chromosomes
Are dyads visible during mitosis?
Yes, with a microscope. During mitosis, the chromatins condense to form chromosomes, which are visible under a microscope.
Does the number of chromatin in a cell vary depending on the function of the cell?
All cells in a body have equal number of chromatins(hence chromosomes).
What is the description of chromatins?
the readily stainable substance of a cell nucleus, consisting of DNA, RNA, and various proteins, that forms chromosomes during cell division
What is an analogy for plastid?
Plastids in cells are like grocery stores. They are the center of specialized metabolic activities in the cell and are where proteins are stored.

Where do spindle fibers attach to chromosomes?
I am at least 70% sure that they attach to the centriole which binds the chromosome together.Centrioles do not have much to do with chromosomes. Centrioles are found just floating in the cytoplasm, while chromosomes are in the nucleus. Chromatins, strands the chromosomes are make up of, are connected by the centromere. Therefore the spindle fibers probably attach to chromosomes in the nucleus, though I, as well, am not entirely sure.
During which phase of the cell cycle are duplicated chromosomes present?
The S phase in the interphase. Chromosomes are copied in the interphase part of the cell cycle S phase would be the answer. It is during Interphase (G1, S, G2) that they are copied. SO dependant on your answers it's either interphase or S.
What is the difference between DNA and chromomatins?
Chromatins are made up of DNA strands
