2.1 describe with the aid of diagrams the processes involved in mitotic cell division
diagram of process of mitotic division
Stages of mitosis
Interphase - replication, respiration, protein synthesis
----------------------------------------------------------------------------
Prophase - chromatin condenses to form chromosomes
- each chromosome has two sister chromatids attached to each other at a centromere
- centrioles move to opposite poles of the cell and nuclear envelope breaks into small pieces
---------------------------------------------------------------------------
Metaphase - chromosome arrange themselves in middle of the equator
- DNA forming centromere replicate
----------------------------------------------------------------------------
Anaphase - sister chromatids pulled apart then pulled to opposite poles
-----------------------------------------------------------------------------
Telophase - chromatin appears because chromosome uncoil
- nuclear envelope reappears
Cytokinesis - cytoplasm divides
