Glucagon and insulinare peptide hormones that are released by the pancreas. The hormones work to maintain homeostasis within the body by regulating blood sugar. The picture shows the structure of glucagon and insulin Glucagon 2 ***** COCOCCCO Which statement BEST describes glucagon and insulin? O The hormones perform the same functions because they are made of amino acids. The hormones perform different functions because they have different chemical bonds. O The hormones perform different functions because they have different amino acid sequences. The hormones perform the same functions because they have the same original DNA structure.

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.
