Ultrastructure of Human Cells

Hi there! I have an assignment due next week in which I have to explain the various organelles and their purpose in specific human cells (I have to choose 4 specialized cells). I was hoping for some help in finding some good example images that I can reference and explain? I've been trying to find s...

Re: Rna polymerase in work

That's not simple question. Absolutely complete mechanisim is still not known, because it involves many things (varied bonds, ultrastructure of polymerases, thermodynamics, factors and soo onnn). I suggest you to read B.Lewin. ''Genes.VIII''. It is a large book ( almost 1000 pages). ...

As for your second picture: sorry nothing more to add. I prefer to remain silent than to say something stupid. But do let me k...

Re: chloroplast ultrastructure

OK, thanks for your opinion, and i agree with you. And as it's hard to tell with one picture, here is a second one, representing a whole cell containing many of those strange plastids. And to finish, is the bottom-right corner plastid really normal? I thought that regular thylacoids were darker than...
