Its function is to change the shape of lens by contraction or relaxation of muscle; 3. * Protein Classification Fibrous polypeptides arranged in long strands or sheets water insoluble (lots of hydrophobic AAs) strong but flexible Structural (keratin, collagen) Globular The function of a protein is determined by its shape. The shape of a protein is determined by its primary structure(sequence of amino acids). The sequence of amino acids in a protein is determined by the sequence of nucleotidesin the gene (DNA) encoding it. The prokaryotic cells have four main components: Plasma Membrane- It is an outer protective covering of phospholipid molecules which separates the cell from the surrounding environment.

Once upon a time, a long long time ago.. ; The origin sites are targeted by the initiator proteins, which recruit additional proteins that help in the replication process to form a replication complex around the DNA origin. This is the stage where DNA replication is initiated. DNA was in the nucleus but proteins were made in the cytoplasm 2. NOTES: Protein Structure & Function Name: 1.
DNA synthesis is initiated within the template strand at a specific coding region site known as origins.
Figure 19.1: The protein structures [1] To understand the biological function of proteins we would like to be able to deduce or predict the three-dimensional structure from the amino acid sequence. Those with thread-like shapes, the fibrous proteins, tend to have structural or mechanical roles. Proteins have a 3 dimensional shape that is a result of interactions between different amino acids in the protein (tertiary structure). This lecture is about the structure of proteins, and how biological phenomena make sense in light of protein structure.
