Lamina - Function?

Postby dan167 » Tue Oct 09, 2007 7:30 pm

Sorry if this is in the wrong place, didn't know where to put it.

Anyways what is lamina? what is its function?

I know it helps control what enters and leaves the nucleus, but don't under stand how... please help me.

sorry, not quite. the nuclear lamina has a main function of maintaing the shape of the nucleus. it is composed of an intermediate cytoskeletal protein named laminin.

Entering/Leaving the Nucleus

Postby LunarStrain » Fri Oct 12, 2007 5:55 am

Im almost 98% sure it's the nuclear pores that controls what enters and leaves the nucleus. The nuclear pores are embedded within the nuclear envelope and they allow molecules to diffuse freely between the nucleoplasm and the cytoplasm and they control the passage of proteins and RNA-protein complexes

I dont know, hope that helps :?

see my summary of the nuclear envelope if you want to know more:
