WebApr 28, 2024 · Transfer RNAs or tRNAs are molecules that act as temporary carriers of amino acids, bringing the appropriate amino acids to the ribosome based on the messenger RNA (mRNA) nucleotide sequence. In this way, they act as the intermediaries between nucleotide and amino acid sequences. WebmRNA is created during the process of transcription, where an enzyme ( RNA polymerase) converts the gene into primary transcript mRNA (also known as pre-mRNA ). This pre-mRNA usually still contains introns, regions that will not go …
