Answer:

<u>Both</u>:

  • The start codon is often AUG

<u>Eukaryotic cell only:</u>

  • The larger subunit of the ribosome is 60s.
  • The ribosomes initially binds the 5' end of mRNA.

<u>Prokaryotic cell only</u>:

  • The ribosome is 70s
  • Translation occurs in the cytoplasm
  • There are multiple ribosome binding site

Explanation:

  • AUG is the common start codon for both eukaryotic as well prokaryotic cells. In eukaryotic cell, it codes for methionine . While in prokaryotic cell, it codes for formyl methionine.
  • In prokaryotic cell, ribosomes are found in cytoplasm, hence the translation occurs in cytoplasm.
  • Eukaryotic ribosome consists of two subunits; 40s and 60s(larger subunit)
  • Prokaryotic ribosomes have 70s ribososme, which consists of 50s and 20s subuints
  • in eukaryotic cell, 40s ribosome initially binds to the cap at the 5' end of mRNA.
  • Bacterial mRNA contain multiple ribosome binding sites.
