Proteins

Proteins

Proteins. Proteins are long polymers made up of 20 different amino acid monomers They are quite large, with molar masses of around 5,000 g/mol to around 100,000 g/mol They have complex structures with unique 3-D shapes that determine their functions

Replication (not part of transcription/translation)

Replication (not part of transcription/translation)

Before a cell can divide, the DNA in the nucleus of the cell must be duplicated. Since the DNA molecule consists of two complimentary stands, if those two strands separate and the right conditions are present, two new stands that are the compliments of the originals will be produced.
