What stage do the chromosomes condense and thicken and are now see in separate distinct structures?
Chromosomes condense and thicken during the prophase stage of mitosis (or meiosis). In this phase, the chromatin fibers become tightly coiled and coiled, making the individual chromosomes visible as distinct structures under a microscope. Each chromosome consists of two sister chromatids joined at the centromere, preparing for segregation in the subsequent stages of cell division.
What else can I help you with?
Which sequence is correct for mitosis?
The correct sequence for mitosis is Prophase, Metaphase, Anaphase, Telophase. These stages represent the process of cell division where the chromosomes condense, line up in the middle, separate, and then form two distinct nuclei.
What happens after chromosomes condense?
After chromosomes condense during cell division, they align along the center of the cell during metaphase. During anaphase, the sister chromatids separate and move towards opposite poles of the cell. Finally, during telophase and cytokinesis, the cell divides into two daughter cells, each with a complete set of chromosomes.
What are the spindle fibers eventually used for?
Spindle fibers are used to attach to and align chromosomes during cell division. They help to separate the chromosomes into two separate sets, which ensures each new cell receives the correct number of chromosomes.
Can proteins have separate domains with distinct structures and functions?
Yes, proteins can have separate domains with distinct structures and functions. These domains often contribute to different aspects of the protein's overall function, such as binding to other molecules, enzymatic activity, or signaling pathways. The modular nature of domain organization allows proteins to have diverse functional capabilities.
What is the stage that chromosomes separate?
What is Half of the number of chromosomes
Which sequence is correct for mitosis?

Why not easy to observe individual chromosomes during the interphase?
coz in interphase, the chromatin threads are not yet condensed into what is called as chromosomes. they are thread like structures, and make a network called chromatin network. chromatin threads only begin to condense into thicker structures called chromosomes once the process of cell division actually begins
Does the cells chromatin condense into chromosomes during prophase?
Yes, during prophase of mitosis, the chromatin in the cell condenses and becomes visible as distinct chromosomes. This condensation helps to organize and separate the genetic material before cell division.
Chromosomes first become visible during which phase of mitosis?
They first become visible during prophase of mitosis.
Which stage of mitosis Chromosomes decrease in length and leave the nucleus?
During prophase of mitosis, chromosomes condense and become shorter. As mitosis progresses, the condensed chromosomes move to the center of the cell and eventually separate during anaphase.
What are the four phases of mitioses?
The four phases of mitosis are prophase (chromosomes condense), metaphase (chromosomes align at the metaphase plate), anaphase (sister chromatids separate and move to opposite poles), and telophase (chromosomes decondense and nuclear envelopes reform).
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.
What happens after chromosomes condense?
After chromosomes condense during cell division, they align along the center of the cell during metaphase. During anaphase, the sister chromatids separate and move towards opposite poles of the cell. Finally, during telophase and cytokinesis, the cell divides into two daughter cells, each with a complete set of chromosomes.
Why is it important for the chromosomes to condense during mitosis a to facilitate DNA replication B to faciliate chromosome movement Cto faciliate cytokinesis d to facilitate spindle formation?
B. It is important for chromosomes to condense during mitosis to facilitate chromosome movement. Condensed chromosomes are easier to separate and move to opposite ends of the cell during cell division, ensuring that each daughter cell receives the correct number of chromosomes.
How do copies of DNA condense into chromosomes that separate during cell division?
During cell division, copies of DNA condense into chromosomes through a process called condensation. This condensation helps to organize and package the DNA into a more compact structure, allowing it to be easily separated and distributed to daughter cells. The chromosomes then align along the center of the cell and are pulled apart by the cell's machinery, ensuring that each daughter cell receives a complete set of chromosomes.
What happens to chromosomes before the nuclear membrane breaks down in mitosis?
Before the nuclear envelope of a cell breaks down during the mitosis process, the DNA has to be duplicated. After the envelope dissolves, the chromosomes separate, then the cell finally splits.
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.
