Transfer ribonucleic acid (tRNA) is a type of RNAmolecule that helps decode a messenger RNA(mRNA) sequence into a protein. tRNAs function at specific sites in the ribosome during translation, which is a process that synthesizes a protein from an mRNA molecule
Transcription is the first step of gene expression, in which a particular segment of DNA is copied into RNA by the enzyme RNA polymerase. Both RNA and DNA are nucleic acids, which use base pairs of nucleotides as a complementary language.
4. The mRNA molecule to be decoded binds to one subunit of the ribosome, then the other ribosomal subunit binds to both of those. In the process, a tRNA with the amino acid methionine attached docks in the ribosome's P site.
