Genetic disorders are caused by the insertion, deletion, or alteration of segments of dna. however, in order for scientists to be able to determine which genes are faulty, they must first know the normal sequences of dna. in 1990, an international effort began to analyze the human dna sequence. what is the name given to this global research that was completed in 2003?

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
