the amoeba

Post by UDKM » Wed Jun 07, 2006 9:40 pm

Can amoebas live long without a nucleus? I know the amoeba would'nt be able to reproduce and grow without a nucleus.Can the amoeba still perform it's other functions without the nucleus? Like eating bacteria and algea? :?:

Any eukariotic cytoplasm cannot long exist without a nucleus.

I would say that they would be able to live long enough to continue eating something but it is the enzymes signaled by the nucleus that makes the ameoba able to do other things. For example the digestion uses different parts of the ameoba's body to process things. These rely on enzymes to function which come from the nucleus.

Yup, I agree...besides, amoeba needs nuucleolus to complete the enzyme synthesis...because I think that ribosomes are synthesized by its nucleolus.. :lol:

Not true, sieve tube members work very well without a nucleus :wink:

@victor
Ribosomal subunits are made in the nucleus, but it is a mistake to say that the ribosoms themselves are made there, since you can only call it a ribosome when the subunits are united, and that only happens in the cytoplasm, when they meet mRNA
