what is the internal structure of
ultrastructure
why is there a double membrane in the nuclear envelope
To separate the chromatin from the harsh surroundings as the chromatin is very fragile
what is chromatin
it’s dna that has proteins within it that is tightly packed by histones
what can travel through nuclear pores
mRNA and ribosomes
what are 40s and 60s made from
ribosomal RNA
what do 40s and 60s come together for
proteinsynthesis
what are nucleoulous characteristics
densely packed dna and protein, it is also involved in making protein
what is the squiggly part of mitochondrion called
matrix

has enzymes that break down dead or useless organelles
