In bacteria, which factor recycles ribosomal subunits after termination?

Explanation:
In bacteria, the ribosome recycling factor handles resetting the ribosome after termination. It works with EF-G and GTP to split the ribosome into its 50S and 30S subunits and to release the mRNA and the spent tRNA. This recycling step is essential so the ribosomal subunits can be reused for another round of protein synthesis. The other options don’t fit this bacterial role: ABCE1 is the equivalent recycling factor in eukaryotes and archaea, not bacteria; eIF4E is an initiation factor that binds the mRNA cap; DNase is a nuclease that degrades DNA.
