Describe the process by which the cell might export a protein to the rest of your body like insulin. Be sure to include the terms Ribosome,...

is the process by which mRNA is made from DNA within the nucleus. The entire process of transcription can be read here: 


The RNA that is made during moves out a nuclear pore of the nuclear membrane. Once in the cytoplasm the mRNA undergoes translation. During translation, RNA (mRNA, tRNA, and rRNA), ribosomes, and nucleic acids work together to make proteins.

The RNA that is made during moves out a nuclear pore of the nuclear membrane. Once in the cytoplasm the mRNA undergoes translation. During translation, RNA (mRNA, tRNA, and rRNA), ribosomes, and nucleic acids work together to make proteins.


Once the proteins are made via protein synthesis, they need to undergo processing to become either primary, secondary, tertiary, or quaternary structures.


The endoplasmic reticulum is a series of membranes found throughout the cell. The endoplasmic reticulum (ER) can be either smooth or rough. The rough endoplasmic reticulum has ribosomes attached while smooth endoplasmic reticulum do not. The membranes of endoplasmic reticulum form sacs called cisternae. The proteins formed during protein synthesis are folded in cisternae spaces called lumen. Once many proteins collect within an ER, the ER creates a transition vesicle around the proteins. This vesicle then pinches off of the ER. The transition vesicle is sent to the Golgi apparatus. The Golgi apparatus then packages, transports, distributes, or stores the proteins. Once the Golgi apparatus has completed its work on the proteins, the proteins are surrounded by a secretory vesicle. The secretory vesicle is pinched off into the cytoplasm and delivered to where they are needed within the cell. The secretory vesicle may also attach to the cell membrane, after which its contents are released from the interior of the cell and are delivered to where they are needed within an organism’s body via blood to other modality.

Is there any personification in "The Tell-Tale Heart"?

Personification is a literary device in which the author attributes human characteristics and features to inanimate objects, ideas, or anima...
