- The Signal Sequence Interacts With The Srp
KEY TERMS:Protein translocation describes the movement of a protein across a membrane. This occurs across the membranes of organelles in eukaryotes, or across the plasma membrane in bacteria. Each membrane across which proteins are translocated has a...
- Eukaryotic Rnas Are Transported
KEY CONCEPTS:RNA is transported through a membrane as a ribonucleoprotein particle. All eukaryotic RNAs that function in the cytoplasm must be exported from the nucleus. tRNAs and the RNA component of a ribonuclease are imported into mitochondria. mRNAs...
- Messenger Rna Is Translated By Ribosomes
KEY TERMS:The ribosome is a large assembly of RNA and proteins that synthesizes proteins under direction from an mRNA template. Bacterial ribosomes sediment at 70S, eukaryotic ribosomes at 80S. A ribosome can be dissociated into two subunits. A ribonucleoprotein...
