Ribosome Subunit Binding, Start Site Recognition, and Release Factor

Subunit Binding

• Large subunit can bind to the small subunit to form a functional ribosome.

Start Codon Recognition

• The mechanism starts at the designated start codon, not at the very beginning; the genetic code determines the start site and reading frame.

• The phrase “the code” indicates dependence on the genetic code for initiating translation.

Release Fact or and Termination

• Release factor is the factor involved in recognizing stop codons and triggering peptide release.

Reading Frame and Selection

• Selection (reading frame) is essential to ensure translation proceeds in the correct frame from the chosen start site.
