Ribosome Flashcards
What causes cytoplasmic basophilia when present in large amounts?
Ribosomes
Cytoplasmic basophilia is a staining property indicating high RNA content.
What are ribosomes described as in electron microscopy?
Small electron dense granules
This description highlights their compact structure and visibility under electron microscopy.
What are the two main types of ribosomes?
- Free ribosomes (free polysomes)
- Attached ribosomes
Free ribosomes function in the cytoplasm, while attached ribosomes are associated with the endoplasmic reticulum.
What are free ribosomes also known as?
Free polysomes
They are clusters of ribosomes connected by a single strand of mRNA.
Where do attached ribosomes become located?
Outer membrane of the endoplasmic reticulum
Attached ribosomes synthesize proteins that are either secreted or incorporated into cellular membranes.
Fill in the blank: Ribosomes that are clusters of 10 or more connected by a single strand of mRNA are called _______.
Free polysomes
This structure allows for the simultaneous translation of multiple copies of the same protein.
