What else can I help you with?
Name the phase of cell division when duplicated chromosomes first appear?
The phase of cell division when duplicated chromosomes first appear is called the prophase. In prophase, the chromatin condenses into visible chromosomes, and the nuclear envelope breaks down, allowing the chromosomes to be more clearly visible.
What phases are chromosomes not visible?
Interphase and Telophase
What cellular events occur during early prophase?
During early prophase, chromosomes condense, becoming shorter and thicker. The nuclear envelope breaks down, allowing the chromosomes to be more accessible. The mitotic spindle begins to form, consisting of microtubules that will eventually attach to the chromosomes.
How can prophase and telophase be considered opposites?
Prophase is when chromosomes group together and prepare for division, while in telophase two new nuclei are formed. telophase is the first step of mitosis; telophase is the fourth step (last).
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.
How many chromosomes do human have in prophase?
Humans have 46 chromosomes in prophase, which consists of 23 pairs of chromosomes. During prophase, the chromosomes become more condensed and visible as they prepare for cell division.
During which phase does the chromatin condense into chromosomes?
The chromosomes coil up and condense during prophase
What stage does chromatin condense to chromosomes?
During mitosis, chromosomes are in their most condensed form during metaphase
What phase does the chromosomes condense into chromatids?
prophase
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 stage mitosis is it when chromosomes shorten and thicken and the nuclear membrane begins to disappear?
The stage of mitosis where chromosomes shorten and thicken and the nuclear membrane begins to disappear is prophase. During prophase, the chromatin condenses into distinct chromosomes and the nuclear envelope breaks down, allowing the chromosomes to interact with the spindle fibers.
In phases of mitosis how many chromosomes does the parent cell have during prophase at the start of mitosis?
During prophase at the start of mitosis, the parent cell has a diploid number of chromosomes, which consists of a complete set of chromosomes from both parents. This means that if a human cell has 46 chromosomes prior to mitosis, it would have 46 chromosomes during prophase as well.
How many chromatids are visible at prophase?
It depends on the organisms. In humans there are 46 double chromosome, which are called sister chromatids. There are a total of 92 sister chromatids, which will eventually separate into individual chromosomes during anaphase of mitosis.
Can chromosomes be seen in a cell that is observed in prophase?
Yes. During prophase the chromosomes condense to prepare for cell division.
What phase does condensation and shortening of chromosomes occur?
Condensation and shortening of chromosomes occur during the prophase stage of mitosis. In prophase, the chromatin fibers condense and coil tightly to form distinct, visible chromosomes.
Name the phase of cell division when duplicated chromosomes first appear?
The phase of cell division when duplicated chromosomes first appear is called the prophase. In prophase, the chromatin condenses into visible chromosomes, and the nuclear envelope breaks down, allowing the chromosomes to be more clearly visible.
What is the phase of mitosis when chromosomes become visibly shortened and thickened?
Prophase
