eukaryotic cells. Classify each statement according to whether it occurs in eukaryotic cells, prokaryotic cells, or both.

Eukaryotic Cell Only Both Prokaryotic Cell Only
1. The start codon is often AUG.

2.There are multiple ribosome binding sites.

3. The ribosome is 70S.

4. The large subunit of the ribosome is 60S.

5. Translation occurs in the cytoplasm.

6. The ribosome initially binds the 5' of mRNA.

Respuesta :

Answer:

Both:

  • The start codon is often AUG

Eukaryotic cell only:

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

Prokaryotic cell only:

  • 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.
