Document Summary
Which of the follow must pass through a nuclear pore in order to get from where it is synthesized to where it functions? rrna* Polya polymerase is made in the cytoplasm and functions in nucleus by adding poly a tails rrna functions out side made inside trna made inside functions outside. Synthesis of membrane proteins is targeted to the er by a pepetide tag that is the fist to emerge from the ribosome. In the coding region because it has to appear as part of the final protein product. Micro rna transcribed from a gene in the nuceus then it leaves the nucleus and pairs with itself. Associates with a protein called dicer it cuts up rna into smaller pieces and attracts the attention of more protiens that bind to this now single stranded rna they base pair with target mrna. Mirna are complimentary to specific mrna, bind to them and stop them.
