Synthesis of proteins in Euk. cells

AI Thread Summary
The nucleolus, located within the nucleus of eukaryotic cells, is responsible for synthesizing ribosomal RNA (rRNA) and assembling ribosomal subunits. These subunits are then transported to the cytoplasm, where they combine with messenger RNA (mRNA) to facilitate protein synthesis. mRNA is transcribed from DNA in the nucleus and exported through nuclear pores for translation. The process from gene expression to ribosome formation is complex but essential for protein production. Understanding these mechanisms is crucial for grasping cellular functions in eukaryotes.

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.
 
I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
