Nucleus Flashcards
What part of the nucleus contains genetic material
chromatin (a complex of DNA and histone proteins) which is the genetic material of the cell
Present in all eukaryotic cells what separates the nucleus and cytoplasm
, the nucleus is relatively large and separated from the cytoplasm by a double membrane (the nuclear envelope) which has many pores
Nuclear pores are important channels for allowing
allowing mRNA and ribosomes to travel out of the nucleus, as well as allowing enzymes (eg. DNA polymerases) and signalling molecules to travel in
the nucleus contains chromatin what is that
(the material from which chromosomes are made)
Chromosomes are made of sections of
linear DNA tightly wound around proteins called histones
Usually, at least one or more darkly stained regions can be observed – these regions are individually termed
‘nucleolus’ (plural: nucleoli) and are the sites of ribosome production
