Final answer:

The eukaryotic elongation factor analogous to prokaryotic EF-Tu and EF-Ts is eEF-1. It has similar functions in delivering charged tRNAs to the ribosome and regenerating GTP from GDP for the elongation process during protein synthesis in eukaryotes.

Step-by-step explanation:

The eukaryotic elongation factor that corresponds to the prokaryotic EF-Tu and EF-Ts is known as eEF-1. In eukaryotes, the elongation process during protein synthesis involves eEF-1, which plays a role similar to that of EF-Tu and EF-Ts in prokaryotes. Specifically, eEF-1A (similar to EF-Tu) delivers the charged aminoacyl-tRNA to the A site of the ribosome, and eEF-1Bα (analogous to EF-Ts) functions to regenerate eEF-1A-GTP from eEF-1A-GDP.The translation process in both prokaryotes and eukaryotes consists of three main stages: initiation, elongation, and termination. Eukaryotic translation involves complex formation with various initiation factors and the distinct feature of a cap-recognition mechanism that leads the ribosome to the start codon of the mRNA. Elongation then proceeds similarly in both eukaryotes and prokaryotes, involving the A, P, and E sites of the ribosome where respective tRNAs bind and peptide bonds are formed.
