Respuesta :
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 nucleotides in the gene (DNA) encoding it.
The shape of a protein molecule directly determines its functions inside and outside of cells
Further Explanation:
Proteins are the product of decoding process that begins with the information in cellular DNA. Proteins compose motor and structural elements in the cell, and they act as a catalyst in variety of reactions that take place in living things. In DNA, each gene is code for unique structure of protein and they attached to each other by different fold and bonds into array of three dimensional structure. The conformation or folded shape of protein depends on linear sequence of amino acid of the protein.
The functions of proteins are:
- Act as catalysts
- Transport molecule
- Store molecules
- Provide mechanical support
- Immune protection,
- Transmit nerve impulses
- Control differentiation and growth.
Proteins are mainly composed of small monomers which are referred as amino acid. These proteins folded into three dimensional structures. The major function of protein is determined by three dimensional structures and they are responsible for specific interaction and function. The component of protein in DNA replication surrounds a portion of DNA double helix. The protein structure allows large part of the DNA is to be copied without the replication machinery detaching from the DNA.
