ribosomes

=__**Ribosomes**__=


 * functions**: The function of ribosomes is protein synthesis. They are either found freely, in the cytoplasm of the cell or they are found attached to ER (endoplasmic reticulum).


 * location in cell** :ribosomes come in two different types; free and attached.
 * free ribosomes are found throughout the cytoplasm.
 * attached one are found connected directly to the ER.

**where they are found (in general)**: Ribosomes are found in the cytoplasm of both prokaryotic and eukaryotic cells. In eukaryotic cytoplasm, ribosomes are found in the cystol, and are bound to the endoplasmic reticulum as well as the outer membrane of the nuclear envelope.


 * nickname: **another nickname that some call ribosomes are "the protein making factory." They call the ribosomes the protein making factory because that's where all the proteins are made, in the ribosomes.

**distinguishing characteristics**: ribosomes are made up of **two** units. these two units are joined together when the ribosome attaches to the messenger RNA to produce a protein in the cytoplasm.
 * 1) **large subunit**
 * 2) **small subunit**
 * **both units are synthesized by the nucleolus**


 * "friends" (other parts the ribosomes work with)**: one part that the ribosomes work with is RNA (ribonucleic acid).

=__Other facts about ribosomes__:=
 * 1) Ribosome's are the workbenches where proteins get manufactured
 * 2) Ribosome composes 25% of cell mass
 * 3) They get their name from their size
 * 4) When the two units are docked together with a special information unit called messenger RNA, they make proteins
