Nuclear chemistry is a sub-discipline of chemistry that involves the chemical reactions of unstable and radioactive elements where both electronic and nuclear changes may occur. The substance (or substances) initially involved in a chemical reaction are called reactants or reagents. Chemical reactions are usually characterized by a chemical change, and they yield one or more products, which usually have properties different from the reactants.
WRONG. In translation: Ribosomal ribonucleic acid (rRNA) is the central component of the ribosome, the protein manufacturing machinery of all living cells. Its function is to provide a mechanism for decoding mRNA into amino acids.ranscription is the synthesis of an mRNA molecule using a DNA molecule for a template. That mRNA molecule then goes on to complete translation in the ribosome.
1 Roles of mRNA, tRNA, rRNA. 2  mRNA (messenger RNA): contains codons that code for the peptide sequence. 3  tRNA (transfer RNA): contains the anticodon on the tip and the corresponding amino acid on the tail. 4  Link the correct amino acid to its corresponding mRNA codon through codon-anticodon interaction. Both tRNA (transfer RNA) and rRNA (ribosomal RNA) are products of transcription. 2  However, they do not serve as the template of translation. 3  tRNA is responsible for bringing in the correct amino acid during translation. 4  rRNA makes up the ribosome, which is the enzyme responsible for translation.
