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 . I read many biology websites and campbell biology 9th edition to figureout the question. but I didn't find something that give me a hint. http://www.sysbio.or...re1hswfinal.pdf
