Which is the purpose of transfer rna?
a. to code for protein synthesis
b. to carry the synthesized genetic information from the nucleus to the ribosomes
c. to synthesize proteins from rna
d. to bring amino acids to the ribosomes to be assembled into proteins

a. to code for protein synthesis

RNA, also known as Ribonucleic acid, is the molecule that is used when coding and decoding genetic information. It similar to DNA and is assembled as a chain of nucleotides. An error in the coding of RNA can lead to the mutation of the genetic information or DNA. This means that the protein will not function as it should and lead to genetic defects in a species. Probably the best example of this is Down's Syndrome. This occurs in humans when there is an extra chromosome in the DNA.
