Difference Between 70S And 80S Ribosomes/ tabular form

Ribosomes are very important cellular organelles that have the task of synthesizing proteins. Proteins perform many functions in our bodies, from repairing cell damage to providing structural support. 70S And 80S Ribosomes/ tabular form

Life as we know it is classified into prokaryotes and eukaryotes, each with its own special ribosomal structure. Eukaryotic ribosomes are called 80S ribosomes, while prokaryotes, like bacteria, have a smaller version called 70S ribosomes.

Read on to explore more differences between the two.

70S vs 80S ribosomes 70S And 80S Ribosomes/ tabular form
Ribosome 70S 80S ribosome
Idea In prokaryotes like bacteria. It also occurs in eukaryotic cells. It occurs exclusively in eukaryotic cells.
Location It is found freely within the cytoplasm of prokaryotes. They are also found in eukaryotic cell organelles such as mitochondria and chloroplast It is found within the cytoplasm or attached to the endoplasmic reticulum.
Synthesis Synthesized within the cytoplasm of prokaryotes. Synthesized within the nucleolus
Subunits Small 30S and large 50S Small 40S and large 60S
RNA 3 RNA molecules 4 RNA molecules
Weight 2.7-3.0 million daltons 4.0-4.5 million daltons
Sedimentation coefficient 70 80
Number of proteins 55 protein molecules, with 34 in the largest subunit and 21 in the smallest subunit 73 protein molecules, 40 in larger subunits and 33 in smaller subunits
Number of amino acids Around 8,000 Around 16,000
RNA to protein ratio 2: 1 (plus RNA) eleven
Influence of antibiotics Antibiotics inhibit protein synthesis Antibiotics  do not  inhibit protein synthesis

What are ribosomes 70S And 80S Ribosomes/ tabular form

Ribosomes were first discovered in 1955 by the Romanian-American biologist George Emil Palade . Ribosomes are the cellular alleles that are present in prokaryotic and eukaryotic cells. In fact, they are the most abundant. They are made up of RN and protein. It is also worth mentioning that these are made in the core.

In terms of its structure, ribosomes are mainly made up of a major unit and a minor subunit. The largest subunit being twice the smallest.

The functions of ribosomes are basically that of protein synthesis or the translation process
