Synthesis of proteins in Euk. cells

[lha08]

Homework Statement

I'm a little confused as to how the nucleolus in a eukaryotic cell manages to synthesize proteins. For example, in the nucleolus, does it contain DNA that it uses to synthesize ribosomal RNA, which then synthesizes ribosomal subunits? Then the ribosomal subunits go out into the cytoplasm to react with mRNA to form the protein? Like where does the mRNA come from...I don't think it comes from the nucleolus...maybe the nucleus?

lol have you taken general biology?

mRNA is transcribed from DNA, which is in the nucleus lol. it's then exported through nuclear pores to be translated into proteins.

the nucleolus is in the nucleus and it's primary purpose is to make ribosomes.

the actual process from gene to ribosome is very complex.

" For example, in the nucleolus, does it contain DNA that it uses to synthesize ribosomal RNA, which then synthesizes ribosomal subunits? Then the ribosomal subunits go out into the cytoplasm to react with mRNA to form the protein? "

this is about correct.
