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...

have a look at these:

ask if somthing is not clear?

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

[mith]

Doesn't mitochondrion have their own ribosomes?

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?

Great links Poison ! I liked the slide show best.

[Poison]

Thanx. I liked it too. some links were like games so I thought that it can be enjoyable.

[Sinead Ryan]

yes the slide show link was very good...and simple enough foe even me to understand.... thanks a million!!!!

[Poison]

You're welcome.

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.
