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.
Ribosomal RNA, or rRNA, is a part of the ribosome that plays a direct role in linking protein building blocks called amino acids. Humans have four kinds of rRNAs. Transfer RNA, or tRNA, decodes the genetic information held in the mRNA and helps add amino acids to a growing protein chain.Scientists estimate that human cells have more than 500 different tRNAs.icroRNA, or miRNA, is a tiny piece of cellular RNA that regulates protein production by binding to mRNA and blocking its ability to function. Scientists have uncovered hundreds of miRNAs in humans, and they estimate that miRNAs regulate more than half of our protein-coding genes.
