I'm learning RNA now and I am confused about polypeptide and ribosome. I know that Polypeptide is composed of amino acids. Protein is composed of one or more polypeptides.
I checked the wikipedia and found the following description about Ribosome.

"A ribosome is a small, dense organelle in cells that assembles proteins."

So, does that mean, Ribosomes are composed of Proteins >>> are composed of Polypeptides >>> are composed of Amino Acids?

Based on the above, my understanding about mRNA and rRNA turned out to be this.

mRNA codes for polypeptides, and after mRNA, the rRNA begins to funtion in coding the Polypeptides to form Protein which eventually becomes Ribosomes. Is my understanding right?

also, which organism, salamander or pea, shows time needed to complete mitosis most like an onion cell?
Salamander spends 60 min. in prophase, 50 min. in metaphase, 6 min. in anaphase, and 70 min. in telophase.
pea cells spend 80 min. in prophase, 40 min. in metaphase, 4 min. in anaphase, and 12 min. in telophase.

as opposed to...
an onion cell, which spends 125 min. in prophase, 25 in. in metaphase, 19 min. in anaphase, and 38 min. in telophase, out of 720 min. total? (that's 720 min. including time for interphase)

and why might these 2 organisms (the onion cell & pea or the onion cell & salamander) whichever is more similar, require similar times to complete mitosis?
