Which of the following describes a role that ribosomes assume in the production of proteins?   a)transports nutrients from inside the cell to the cell membrane to be used in making proteins. b)produces energy for the cell to use during protein synthesis. c)translates mrna into a specific amino acid chain.    d)rids the cell of leftover amino acids once the proteins have been synthesized. 

Your answer would be C, hope this helps, good luck. 

Cells of an organism tell each other when predators are near.

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of  amino acids  , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in  genes  . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called  transcription  ), and the mrna is transported to the  ribosome  . protein synthesis, also called  translation  , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the  nucleotides  of mrna three by three, in units called  codons  , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the  amino acid  chain goes on to be processed and folded to make the final, functional protein
