Question

What is the molecule that brings amino acids to the ribosomes to be assembled into proteins??

Answer 1

The molecules that brings amino acids to the ribosomes are the tRNA molecules.  

Answer 2

The molecule that brings amino acids to the ribosomes to be assembled into proteins are known as tRNAs (transfer RNAs). RNA molecules are of three types:

1) mRNA (messenger RNA)

2) tRNA

3) rRNA (ribosomal RNA)

All these three RNA molecules help in protein synthesis i.e. translation.

mRNA gets the message from the DNA to make a protein with a particular amino acid sequence. rRNA on the other hand provides the site for the synthesis of a particular protein whereas tRNA brings the amino acids from the cytosol to the site of protein synthesis. mRNA, tRNA and rRNA basically form a complex so as to accomplish protein synthesis.
