What is the role of the spindle fibers during mitosis?
Spindle fibers form a protein structure that divides the genetic material in a cell. The spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells during both types of nuclear division: mitosis and meiosis. During mitosis, the spindle fibers are called the mitotic spindle.
What is the role of the spindle fibers during mitosis quizlet?
During mitosis, the spindle fibers are called the mitotic spindle. Their proteins help to hold the sister chromatids together and also play a role in chromosome editing.is a protein structure on chromatids where the spindle fibers attach during cell division to pull sister chromatids apart.
What is responsible for the separation of chromosomes during mitosis?
The chromosomes are separated by a structure called the mitotic spindle. The mitotic spindle is made of many long proteins called microtubules, which are attached to a chromosome at one end and to the pole of a cell at the other end. The sister chromatids are separated simultaneously at their centromeres.
How many chromosomes are there after mitosis?
What would life be like if there were no cells?
Mitosis is the process by which cells divide. Without it, you could make no new cells. The cells in most of your body would wear out very quickly, greatly shortening your life
Can there be life without cells?
Non-cellular life, or acellular life is life that exists without a cellular structure for at least part of its life cycle. The primary candidates for non-cellular life are viruses. Some biologists consider viruses to be living organisms, but others do not.
What happens if there are no cells?
Cells make up tissues, like connective tissue, skeletal tissue, nervous tissue and fatty tissue. Tissues make up organs like your heart, your liver, your brain, spleen, stomach and so on. With no cells, there are no tissues or organs. Humans would not exist
