Question

28.

Which of the following is the most likely reason that many
ribosomes do not attach to the surface of the rough
endoplasmic reticulum during translation?
They do not make the appropriate anchor protein.
They have a signal/trafficking error.
They have a defect in ribosomal proteins that allow
attachment to the ER.
They are synthesizing cytoplasmic proteins.

Expert Solution

Step 1

A ribosome is an intercellular structure composed of RNA and protein, and it serves as the site of protein synthesis in the cell. The ribosome reads the messenger RNA (mRNA) sequence and converts the genetic code into a specific string of amino acids. These amino acids then form long chains that fold to form proteins. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins. Sometimes, when those proteins are made improperly, the proteins stay within the endoplasmic reticulum.
