The ribosome was first observed as a structure when people like George Palade and Philip Siekevitz applied the electron microscope to cells in the 1950's using various cell stains involving heavy metals, such as osmium. The ribosome was discovered as a machine that synthesizes proteins by work of many people, leading to the identification of mRNA and tRNA by Paul Zamecnik, Mahlon Hoagland, and others.

What else can I help you with?
Who discovered ribosomes and when?
Ribosomes were first observed in the mid-1950s. Romanian cell biologist George Emil Palade observed them.
What are Palade particles and why are they called so?
Palade particles are ribosomes present within the cytoplasm of a cell, named after the scientist George Palade who discovered them. These particles are responsible for protein synthesis in the cell by translating mRNA into proteins.
Who was the scientist who discover Ribosomes?
Romanian cell biologist George Emil Palade discovered. The year was 1950
What country were the scientists who discovered the ribosomes from?
Romanian cell biologist George Emil Palade observed in 1950s. Country is the Romania
When were ribosomes first discovered?
Romanian cell biologist George Emil Palade observed in 1950s. He won Nobel prize in 1974
What has been discovered about plant cells?
it has been discovered that they have a cell wall, cell membrane, mitochondria, chloroplast, endoplasmic reticulum or ER, Ribosomes and many more we learned this in 7thy grade hope this helps.
The sites of protein synthesis are?
Protein synthesis occurs at ribosomes, which can be found in the cytoplasm of a cell. In eukaryotic cells, proteins can also be synthesized on ribosomes located on the rough endoplasmic reticulum.
What tiny organelles are attached to the ER?
ribosomes
What are unattached ribosomes in the cytosol called?
Free ribosomes.
What are the differences between prokaryotic ribosomes and eukaryotic ribosomes?
Prokaryotic ribosomes are smaller (70S) compared to eukaryotic ribosomes (80S). Prokaryotic ribosomes consist of a 30S and a 50S subunit, while eukaryotic ribosomes consist of a 40S and a 60S subunit. Prokaryotic ribosomes have fewer proteins compared to eukaryotic ribosomes.
What organelles read codes genetic measages?
Ribosomes are the organelles that read coded genetic messages. Ribosomes can be found in all living cells.
What type of cell is ribosomes?
Ribosomes are organelles. All cells have ribosomes.
