What else can I help you with?
What events occur during prophase?
The nucleoli disappears; the nuclear membrane breaks down; the mitotic spindle appears and the centrioles begin moving towards opposite ends of the cell.
What does slight antalgic gait?
This would indicate that most likely the person or animal is demonstrating a visible asymmetry during walking as a result of pain.
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.
Do raccoons hibernate in Ontario?
No, raccoons do not hibernate anywhere. They continue to be active and forage for food during the winter. If the snow becomes too deep for foraging or the temperature becomes too cold, they stay in their den and sleep and emerge again when conditions improve.
When is the best season to see pegasus?
Pegasus is a constellation that can be seen best in the Northern Hemisphere during the autumn months, particularly in September and October. During this time, Pegasus is visible in the night sky and is easiest to spot when looking eastward.
During which step in mitosis do the chromosomes get attached to the spindle apparatus?
During the metaphase stage of mitosis, the chromosomes become attached to the spindle apparatus.
The spindle apparatus disintegrates during .?
Telophase
What cell parts are more clearly visible when a cell is dividing?
During cell division, structures like the chromosomes, spindle fibers, and centrioles are more clearly visible. Chromosomes condense and can be seen as distinct entities, spindle fibers form a dynamic network between the centrioles, and the centrioles organize the spindle apparatus.
What does a spindle apparatus do in mitosis?
Separation of chromatids during anaphase .
What part of the chromosome is the spindle apparatus attach?
The spindle apparatus attaches to the centromere region of the chromosome. This is where the kinetochore proteins are located, which help in the attachment of spindle microtubules to the chromosome during cell division.
What functions to separate chromatids during cell division?
spindle apparatus
During mitosis the centrioles form or organize the mitotic apparatus which is known as what?
spindle
When does the nuclear membrane disappear during mitosis?
The nuclear membrane disappears during prophase of mitosis. This allows the chromosomes to be condensed and move freely within the cell. At the end of mitosis, during telophase, the nuclear membrane reforms around the separated chromosomes.
A centriole with radiating fibers active during cell division?
The centriole with radiating fibers is known as the aster. Asters are involved in the organization of the mitotic spindle during cell division, helping to position and align the chromosomes. They also play a role in anchoring and moving the spindle apparatus.
How does spindle apparatus distribute chromosomes to the daughter cells?
The spindle apparatus is responsible for aligning and segregating chromosomes during cell division. The microtubules of the spindle apparatus attach to the centromere of chromosomes and actively move them to opposite poles of the cell during anaphase of mitosis or meiosis. This ensures that each daughter cell receives the correct number of chromosomes.
When does the spindle attach to the kinetochores?
The spindle attaches to the kinetochores during prometaphase, where the microtubules from the spindle apparatus interact with the kinetochores on sister chromatids. This attachment is essential for proper chromosome alignment and segregation during cell division.
What is the function of the spindle apparatus?
Microtubules
