Ribosomes structure and function essay help

Ribosomes are non-membranous, basophilic granules, rich in Ribonucleic acid and distributed in the cytoplasm of both prokaryotes and eukaryotes. They were first isolated and named by Palade Ribosomes are made up of RNA and proteins and are the center of protein synthesis.

These are the smallest cell organelles with a diameter of about - A0. They occur either freely in the cytoplasm or attached to the endoplasmic reticulum or nuclear membrane of eukaryotic cells. A large number of ribosome occurs in a single cell.

ribosomes structure and function essay help

Each ribosome has two subunits: The two subunits dissociate below this critical concentration of magnesium ion. The 70s ribosome is constituted by 30s smaller subunit and 50s larger subunit. During protein synthesis many ribosome arrange in a chain on a common messenger RNA mRNA strand and are called as polysomes or poly ribosome Ribosomes are chemically composed of ribosomal RNA rRNA and various types of proteins molecular weight ranging from 6ooo to In eukaryotes, 60s subunit contains 28s rRNA sooonucleotides5.

The 40s subunit of eukaryotic ribosome has 18s r RNA and 33 Proteins. Ultra structure The smaller subunit consists of a head, a base and a platform. The platform separates head from base by a cleft. The larger subunit has a ridge, a central protuberance and a stalk.

The ridge is separated from central protuberance by a valley. When the two subunits. Ribosome provides the sites for protein synthesis translation. This is done by the ribozyme RNA - enzyme activity of larger subunit site.

These are single unit membrane bound small spherical bodies.
