1
New cards

universal organelles

  • found in all cells

  • serve as site of protein synthesis

2
New cards

two subunits of ribosomes

  • rRNA and proteins

  • join only when actively synthesizing a protein

3
New cards

where are subunits synthesized

nucleolus, then move through nuclear pores to cytoplasm

4
New cards

two types of ribosomes

70s - prokaryotes

80s - eukaryotes

5
New cards

free-ribosomes

  • proteins found in the

    • cytoplasm

    • nuclear proteins

    • mitochondrial proteins

6
New cards

membrane-associated ribosomes

  • SYNTHESIZE PROTEINS ON THE ROUGH ENDOPLASMIC RETICULUM

  • proteins to be in a membrane

  • proteins sent to lysosomes or vacuoles

  • destined for export

7
New cards

mRNA

  • messenger RNA

  • makes complimentary copies

  • gives instructions on how to build proteins

8
New cards

tRNA

  • transfer RNA

    • brings correct amino acid to ribosome

9
New cards

rRNA

  • ribosomal RNA

  • component of ribosomes

  • catalyze peptide bond formation between amino acids
