SIR IN WHICH PHASE DOES SPINDLE FIBRES START FORMING AND HOW??? I DIDNT UNDERSTAND THAT CONCEPT.
Asked by rajkoth20002 | 19th Jul, 2017, 07:56: PM
Spindle fibres are a part of the spindle apparatus required during cell division. The spindle apparatus consists of spindle fibres, motor proteins, chromosomes, and in some cells, structures called asters. Spindle fibres are necessary to equally divide the chromosomes in a parental cell into two daughter cells during both types of nuclear division: mitosis and meiosis. During late prophase, spindle fibres begin to form from each daughter centriole to the centre of the cell.

- Draw anaphase stage with 3 pairs of Chromosomes. Which is the resting phase? Is it interphase or late G1 phase?
- What are the functions of asters? What is the difference between centrioles and centrosomes? What is a homologous chromosome? Define it.
- what is mitosis
- Why spindle fibre form
- What is M phase?
- How does the furrow in the animal cell deepen?
- why does the thickning of chromatin material thicken during the interphase?
- What is the shortest test of mitosis
- What is 'M' phase
- You did not mention KINETOCHORE which connects the chromatids to the spindle fibres to pull them towards the poles.......Please confirm.
