Answer:
Moving genetic code from the nucleus to a ribosome
forming part of the ribosome
Carrying amino acids to a ribosome
controlling splicing by marking intron and exon sequences
Explanation:
Ribonucleic acid (RNA) is a key molecule that has diverse biological functions. In the first place, the messenger RNA (mRNA) is an RNA version whose function is to transmit the code from the DNA within the nucleus to the cytoplasm during protein synthesis. Second, the ribosomal ribonucleic acid (rRNA) represents a structural component of ribosomes where proteins are synthesized. Third, the transfer ribonucleic acids (tRNAs) represent another important class of RNA version that attach amino acids to transport them to the ribosomes in order to decode an mRNA into a protein. Finally, RNA splicing is the processing of RNA to eliminate non-coding introns from the precursor mRNA (pre-mRNA) molecule to form the final mature mRNA transcript.
