Ribonucleic acid ,or RNA, is one of the three major macromolecules (along with DNA and proteins) that are essential for all known forms of life. Like DNA, RNA is made up of a long chain of components called nucleotides.
The basic building block of any substance is the atom. Every element and compound is made up of one or more atoms. In making up of the atom an atom is made up of only one nucleus but can have several shells. Within the nucleus protons and neutrons are present.Every element has a specific number of protons.toms are tiny units of matter. All matter are made up of matter that occupies space and is made up of atoms. Atoms are the smallest particle of an element that can join up in whole numbers to form molecules.
Report Abuse. Yes, atoms make up molecules. For example, water molecules are made up of two hydrogen atoms and one oxygen atom (represented as H2O) and table salt is made up of one sodium atom and one chlorine atom (represented as NaCl).lements-hydrogen, oxygen, chlorine... All the elements that exist are indicated in the Periodic Table. These elements exist as single atoms (e.g. neon, argon), two atoms covalently joined together (e.g. oxygen, hydrogen) and as macromolecules (e.g. diamond).
