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 [...]
The following points highlight the top three types of non-Genetic ribonucleic acid (RNA). The types are: 1. Messenger RNA (MRNA) 2. Ribosomal RNA (rRNA) 3. Transfer RNA (tRNA). Type # 1. Messenger RNA (MRNA): Monod and Jacob (1961) coined the term 'messenger RNA' to describe the template RNA that carries genetic information for protein synthesis from nuclear DNA to ribosomes [...]
