Ribosomes and Protein Synthesis

Non-membranous organelles that build proteins in cells.

Ribosomes found in bacteria and archaea, with 70S sedimentation.

Ribosomes found in plant and animal cells, with 80S sedimentation.

The sedimentation rate of prokaryotic ribosomes.

The sedimentation rate of eukaryotic ribosomes.

Carries the genetic code from DNA to the ribosome for protein synthesis.

Ribosomes that produce proteins used inside the cell.

Ribosomes that synthesize proteins for export or cell membrane.

Ribosomes are found in both prokaryotic and eukaryotic cells, including cytoplasm, mitochondria, and chloroplasts in eukaryotes.

Ribosomes are the cellular protein synthesis machines, producing the proteins of a cell.

Ribosomes have two subunits: a large and a small subunit, that assemble for protein synthesis.

The large subunit is typically bigger than the small subunit, working together like a team.

Ribosomes are made of ribosomal RNA and proteins; the major component is rRNA.

Prokaryotic (70S) and eukaryotic (80S) ribosomes differ in their structure, reflecting their origin.

Ribosomes that float freely in the cytoplasm and produce proteins used inside the cell.

Ribosomes that are attached to the endoplasmic reticulum, producing proteins for use inside or outside of the cell.

The large ribosomal subunit has A, P, and E sites to interact with tRNA during protein synthesis.

Multiple ribosomes can bind to the same mRNA and translate it simultaneously into multiple copies of that protein.
