Info

• Cell fractionation is where a cell are broken up and its components and organelles are separated so that scientist can observe them in isolated form . • It can also be defined as : the separation of homogeneous sets , usually organelles, from a larger population of cells.
What we’ve learned so far using this technique : 1.Mechanism of protein synthesis 2.DNA replication and transcription 3.RNA splicing 4.Muscle contraction 5.Microtubule assembly 6.Vesicular transport in the secretory pathway 7.Importance of mitachondria and chloroplasts in energy interconversions .
