Which statement below best summarizes the role of the dna molecule in cells?

DNA provides the instructions for making proteins.

Explanation:

Deoxyribonucleic acid (DNA) is a macromolecule that contains the genetic information for the development and function of living organism. DNA is composed of 4 bases (adenine, thymine, guanine, cytosine) that form genes. Each gene has a specific sequence of bases that encode a protein. When DNA replicates and forms RNA (which has a complementary base sequence to the DNA that gave it its origin), this molecule is transferred to ribosomes, which are the organelles where protein synthesis takes place. Every three bases, a different amino acid is coded. Many amino acids together form a protein. So, the genetic code dictates which proteins are created according to the sequence of nucleotides in DNA genes. This is a direct connection between genes and traits, which is a characteristic determined by proteins.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
