Proteins
We generally tend to think of proteins only from a dietary lens, as a component of what we eat. However, they are among the most important and abundant organic macromolecules in the human body, with diverse structures and functions. Every cell contains thousands and thousands of proteins, each with specific functions. Some help in the formation of cellular membrane or walls, some help the cell to move, others act as messages or signals and flow seamlessly from one cell to another, carrying information.
Protein Expression
The method by which living organisms synthesize proteins and further modify and regulate them is called protein expression. Protein expression plays a significant role in several types of research and is highly utilized in molecular biology, biochemistry, and protein research laboratories.

Transcribed Image Text:Proteins
Proteins are determined by the structure of DNA and RNA. DNA consists of two chains of nucleotides held together by
chemical bonds. Base pairing rules determine how the bases of each chain will bond to one another. RNA also has
repeating nucleotides, bases that are held together by chemical bonds, and specific base pairing rules, but it is a single
strand and has different bases than DNA. The sequence of DNA is rewritten into an RNA copy which then determines the
sequence of amino acids of a polypeptide chain, the primary structure of a protein. A single amino acid is added to the
protein strand for every 3 bases, or codons, in the RNA. The sequence of amino acids determines the way the protein will
fold. The folding of the protein determines its function. The structure of DNA, RNA, and a protein are shown.

The triplet codon used to decipher the amino acids is mostly universal. Each amino acid has more than one codon.
Methionine (AUG) is the initiation codon that starts the translation process. There are 3 codons that stop the translation
process.
