Eukaryotic ribosomes differ from bacterial ribosomes in that the eukaryotic ribosomes multiple choice are smaller in size and require more initiation factors in order to be positioned properly on the mrna. are larger in size and require more initiation factors in order to be positioned properly on the mrna. are smaller in size and require fewer initiation factors in order to be positioned properly on the mrna. are larger in size. are smaller in size.

are larger in size and require more initiation factors in order to be positioned properly on the mRNA

Explanation:

Eukaryotic ribosomes are larger than prokaryotic ribosomes.  60S large sub unit and 40S large sub unit come together to form 80S final unit. It has a mass of 4200 kd. In contrast prokaryotes have 70s ribosome made of 50s and 30s sub units and has a mass of only 2700 kd.

Initiation factors are required at the beginning of translation process. They bind to small sub unit of ribosome to begin translation. Eukaryotes have more initiation factors than prokaryotes. Bacteria usually have initiation factors IF-1, IF-2 and IF-3. Whereas eukaryotes' initiation factor is called as eIF and more than six types are present.

that is wrong, its not thymus.

i know can you plzz me with this question im sorry i didt answer your question i just need hel.
