Consider this animal cell. The organelles in an animal cell are labeled. Part E represents small dots on the nucleolus.

What is the function of the small, dark organelles labeled E?

Six amino acids have side chains that are polar but not charged. these are serine (ser), threonine (thr), cysteine (cys), asparagine (asn), glutamine (gln), and tyrosine (tyr). these amino acids are usually found at the surface of proteins, as discussed in the proteins 2 module.
