What is a scanning electron microscope?
scans surface of cell to help study 3-D structure of the cell
What is are the 3 types of RNA? and what do they do?
messanger RNA- brings instructions from DNA out of nucleus to ribosomes.
ribosomal RNA- binds mRNA and helps to assemble amino acids in correct order
transfer RNA- deleivers amino acids to ribosomes to be assembled into a protein.
