Golgi Apparatus and Its Functions

The Golgi apparatus is a packaging center Golgi apparatus or Golgi body or Golgi complex is a membrane-bound organelle, associated with the processing of proteins It exists in all the cells other than red blood cells It is called after the originator Camillo Golgi. Typically, each cell

Chromatin And Chromosomes

DNA does not exist as a naked double helix in the nucleus of a cell, however, is complexed with proteins to form a great filamentous material called chromatin. In many cells, the chromatin takes place as 46 long filaments called chromosomes. There is a stupendous quantity of

Loose Connective Tissue

Loose connective tissues help to bind together other tissues and form the basic supporting framework for organs. Their matrix consists of a semifluid or jelly-like ground substance in which fibers and cells are embedded. The word “loose” describes how the fibers are widely spaced and intertwined between

Peroxisomes and Its Functions

Peroxisomes or microbodies are the membrane minimal vesicles like the lysosomes. Unlike lysosomes, peroxisomes are pinched off from endoplasmic reticulum and not from the Golgi apparatus Peroxisomes consist of some oxidative enzymes such as catalase, urate oxidase and D-amino acid oxidase.   Oxidative enzymes, as the name

RNA Structure, Function, Synthesis, Types and Interference

There many types of RNA in a cell Nevertheless, we will focus on the three that are straight related to producing proteins: messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA). DNA can not produce proteins without their help. The other RNA types play various regulative
