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 rRNA is located in the cytoplasm of a cell, where ribosomes are found. 2  rRNA directs the translation of mRNA into proteins. 3  tRNA or Transfer RNA. 4  Like rRNA, tRNA is located in the cellular cytoplasm and is involved in protein synthesis. tRNA or Transfer RNA. 2  Like rRNA, tRNA is located in the cellular cytoplasm and is involved in protein synthesis. 3  Transfer RNA brings or transfers amino acids to the ribosome that correspond to each three-nucleotide codon of rRNA.
