I like this question because it reminds me that examiners think objects can exist in 2 dimensions.
Fibronectin is an extracellular matrix glycoprotein, while lamin is an intermediate filament that specifically provides support to the cell nucleus. Don’t confuse lamin with laminin (science hates us clearly); laminin is like fibronectin, an ECM glycoprotein and a major component of the basal lamina of basement membranes.
So... I didn't know what it was so I looked it up... and legit, granum is part of plants.......... really?! lol
Any good material to prepare for this kind of stuffs?
Lamins form a nuclear membrane surrounding DNA. imp for structural support, organizing genome, regulating gene transcription. Defective in Progeria and muscular dystrophy.
