RIBOSOMES Meaning and
Definition
-
Ribosomes are cellular organelles that play a vital role in protein synthesis within living organisms. Found in both eukaryotic and prokaryotic cells, ribosomes are composed of ribonucleic acid (RNA) and proteins. They exist in large numbers within cells and can be found freely in the cytoplasm or embedded within the endoplasmic reticulum.
Ribosomes act as molecular machines responsible for the translation of genetic information from deoxyribonucleic acid (DNA) into proteins. They do so by connecting specific amino acids together in a precise order, determined by the sequence of nucleotides in messenger RNA (mRNA), to form polypeptide chains. This process, known as protein synthesis or translation, is essential for the growth, development, and function of cells and organisms.
The structure of ribosomes consists of two subunits, known as the large and small subunits, which come together during protein synthesis. The small subunit binds to the mRNA, while the large subunit helps catalyze the formation of peptide bonds between amino acids. Ribosomes are highly conserved across different species, indicating their fundamental importance in cellular functioning.
In summary, ribosomes are cellular organelles responsible for protein synthesis. They consist of RNA and proteins, and their primary function is to translate the genetic instructions stored in DNA into functional proteins that carry out various cellular processes. Ribosomes are essential for the growth, development, and proper functioning of all living organisms.

Etymology of RIBOSOMES
The word "ribosome" has a fairly straightforward etymology. It is derived from the combination of two words: "ribo-" and "-some".
The prefix "ribo-" comes from the term "ribonucleic acid" (RNA). RNA is a molecule essential for the coding, decoding, regulation, and expression of genes. It plays a crucial role in the synthesis of proteins, which is a primary function of ribosomes.
The suffix "-some" is derived from the Greek word "soma", meaning "body". In biology, it is commonly used in terms such as "chromosome" and "lysosome" to refer to a distinct structure or organelle within a cell.
So, when combined, the term "ribosome" literally means "RNA body" or "bodies composed of RNA". This accurately describes the nature and composition of ribosomes, which are cellular organelles responsible for protein synthesis.
