Cell division revision articles
- The Cell Cycle and DNA Replication – Cell Division Ep 1
All the cells in multicellular organisms which are capable of division go through a cell cycle – a sequence of phases which incorporates cell growth,… Continue Reading → - Mitosis – Cell Division Ep 2
Mitosis is a method of nuclear division used by multicellular organisms for growth and repair of tissues. Some plants and fungi (and rarely some animals)… Continue Reading → - Binary Fission – Cell Division Ep 3
In the last article we looked at mitosis as a method of cell division. However, mitosis can only take place in eukaryotic cells. Prokaryotic cells,… Continue Reading → - Meiosis – Cell Division Ep 4
Meiosis is a little more complicated than mitosis, and has a different outcome. Meiosis is a method of nuclear division which only happens in the… Continue Reading → - Crossing Over and Independent Assortment – Cell Division Ep 5
In the last article we looked at meiosis – the type of nuclear division that produces haploid gametes in the reproductive organs. Today we’re going… Continue Reading →
