Quick Notes on Golgi Complex:- 1. Structure of Golgi Complex in Cell 2. Origin of Golgi Complex in Cell 3. Function. Structure of Golgi Complex in Cell: Ultra structural analysis reveals the presence of three membranous components: flattened sacs or cisternae, small tubules and vesicles and large vacuoles. The cisternae or lamellae are the most constant elements of the Golgi [...]
Quick Notes on Ribosomes! Structure of Ribosomes in Cell: Ribosomes are cytoplasmic non- membranous ribonucleoprotein granules of 150 -200 A diameter. They have a typical binary and constricted structure with the two units being unequal in size. The prokaryotic and eukaryotic ribosomes are differentiated on the basis of the sedimentation coefficient. These are of two basic types, 70S and BOS [...]
Learn about the difference between Euchromatin and Heterochromatin. Difference # Euchromatin: 1. The chromatin fibres in this region are loosely coiled as compared with hetero chromatic regions 2. Euchromatin is deeply stained in divisional cycle but less stained in interphase. 3. The region is genetically active and contains unique DNA. 4. Euchromatic regions are able to synthesize mRNA in vitro. [...]
