THERMAL PROPERTIES OF WATER

Pure water becomes a solid below 0°C and becomes a gas above 100°C at sea level.

When water contains dissolved compounds, such as salts, its freezing temperature drops below 0°C.

Dissolved compounds also raise the boiling point of water above 100°C.

Nucleotide changes, particularly those at the third position of the codon, that do not alter the amino acid sequence are called synonymous substitutions.

Nucleotide changes in a gene that alter the amino acid sequence of a protein are referred to as non-synonymous substitutions.
