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.
How elements are arranged in the periodic table (General) 1  The chemical elements are arranged in order of increasing atomic number. 2  The rows are called periods and the columns are called groups. 3  Elements with similar chemical properties are in the same group of elements.
