Compared with the trans-Golgi proteins, the cis-Golgi proteins would a. be identical.

b. be shorter in length.

c. be glycosylated and contain amino acid modifications.

d. contain sialic acid.

e. be glycosylated

A. be identical.

C. be glycosylated and contain amino acid modifications.

Explanation:

In comparing the proteins in a cis Golgi area with those in a trans Golgi area, one would discover that: these proteins are identical in nature. The Cis-Golgi proteins are glycosylated and contain modified amino acids while the trans-Golgi proteins amino acids are not modified.

The correct answer is option e. "be glycosylated".

Explanation:

Proteins can either enter to the Golgi apparatus facing the endoplasmic reticulum (cis-Golgi proteins) or facing the plasma membrane on the cell (trans-Golgi proteins). The difference between trans-Golgi proteins and cis-Golgi proteins is that the latter are glycosylated. Glycosylation takes place in the rough endoplasmic reticulum, therefore proteins that enter trough this organelle, most likely undergo this post-translation modification.
