hey could anyone explain to me (as simply as possible) how riobosomes and mitochondrion make proteins??? The books I've read might as well be double dutch for all the help they are...

http://www.emc.maricopa.edu/faculty/far ... OTSYn.html

http://www.eurekascience.com/ICanDoThat/protein_syn.htm

ask if somthing is not clear?

By the way proteins are sythesised by ribosomes. havent heard of mitochondrion. has anyone?

Doesn't mitochondrion have their own ribosomes?

endosymbiosis

Postby 2810712 » Fri Mar 04, 2005 10:21 am

Ya, according to endosymbiotic theory mitochondria and chloroplasts were bacteria and then they got adapted for endosymbiosis [ symbiosis inside a cell] naturally mitochondria have their own DNA ribosomes etc... but I haven't heard of any chloroplast having ribosomes.. why is it so?

Chloroplast ribosomes..

Postby rakey » Wed Mar 16, 2005 8:47 pm

well, the reply to enquiry of chloroplast having ribosomes,
They do have ribosomes!! however, the ribosomes of chloroplasts are more prokaryotic in nature (with regardsto size, biochemical characters, etc) than to eukaryotic ribosomes. It probably has to do with the evolutionary process, where the eukaryotic plant cells entered into a endosymbiotic realionship with a prokaryotic cell.

Well in theory chloroplasts where once bacteria and then moved into the cell.
