Hello All,
I was wondering if anyone  help me to answer  this question which is;
If  you are a cell and  I told you to threw one of these organisms which is ribosome or DNA. Which one you will choose and why?
Thanks All

Clearly a homework question so I have moved your post.

How about you provide some sort of answer rather than us just giving you the answers.  Note that neither ribosomes or DNA are organisms or even organs (presuming you made a typo).

DNA and Ribosomes both of them are organelles . DNA is inherited  from the partents and DNA in the eukaryotic cell ;it  control the development of the cell and know how to function in the cell.DNA found in the nucleous and it allow  DNA for replication.However, DNA after replication  is doing  transcribion to produce RNA. The  pre-mRNA synthesized at  the end transcription which need some modification after it complete the transcribition .the m-RNA move to the cytoplasm after it checked its transcribited .

mRNA carry copies of genetic meterials that are used to assemble amino acids to produce proteins/polypeptide chains.However, Ribosome for eukaryotic cell is found in the cytoplasm and the active  ribosome contain of r-RNA +protein. The ribosome have  catalytic properties and it has its own structure . Ribosome (two subunits) hold the m-RNA. The t-RNA(is

small ribosomal subunit to recogize the5' of the m- RNA)  The small ribosomal subunit scans RNA until it reaches the AUG codon and it combines both of the  to  large and small subunit  to produce protein.That's why I dont know which one to  threw it , both of them are important without DNA there is no RNA for ribosome to make protein  and without prothein there is no function.

　
Thats what I know , thank you
