As in DNA replication, RNA is synthesized in the 5' â 3' direction (from the point of view of the growing RNA transcript). Only one of the two DNA strands is transcribed. This strand is called the template strand, because it provides the template for ordering the sequence of nucleotides in an RNA transcript.
The properties of the chemical elements are summarized on the periodic table, which organizes the elements by increasing atomic number into rows (periods) in which the columns (groups) share recurring (periodic) physical and chemical properties.
Our periodic table of chemical elements presents complete information on the chemical elements including the chemical element symbol, atomic number, atomic weight and description. The links below lead to the detailed description of most well known chemical elements. Our periodic table information can be useful for chemistry and physics students, as well as science researchers.You can test your Periodic Table knowledge with our Periodic Table Quiz.
