Function
What are the two subunits of ribosomes?
Large subunit and small subunit
Where are ribosomes found?
Rough ER and chloroplasts
DNA is copied onto an RNA molecule
Transcription
What do ribosomes build?
Proteins
Where are free ribosomes?
Floating in the cytosol
mRNA makes a polypeptide and folds into a protein
Translation
What functional proteins are formed?
Enzymes, hormones, structural proteins, and transport proteins
Where are bound ribosomes?
3 nucleotides in DNA or RNA that have genetic code
Codon
What do they read and translate?
Instructions from the RNA
What is the size difference between prokaryotic and eukaryotic ribosomes?
Prokaryotic ribosomes are smaller
Bring amino acids to the ribosome and match codons
Transfer RNA
What do they fight off? How?
Infection, by targeting ribosomes with different structure.
What are ribosomes made of?
rRNA and proteins
What do subunits do once translation is complete?
Disassemble
