Answer:

PCBs and DDT are chemicals that were banned more than 30 years ago, but our air, water, land, and bodies are so contaminated that decades of cleanup efforts have yet to eliminate their threats to our health. Today, food is one of the most likely exposure routes to PCBs.

Dna codes for the sequence of amino acids in the primary structure of a protein, but not for sugars or lipids. This is because?
s2008m [1.1K]

Proteins are the main structural and functional components of cells.

Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid. The mRNA sequence is thus used as a template to assemble in order the chain of amino acids that form a protein.

The sequence of a protein is determined by the DNA of the gene that encodes the protein change in the gene's DNA sequence may lead to a change in the amino acid sequence of the protein. The sequence of amino acids of a protein determines protein shape, since the chemical properties of each amino acid are forces that give rise to intermolecular interactions to begin to create secondary structures, such as α-helices and β-strands.
