The DNA double helix is composed of two strands of DNA;

each strand is a polymer of DNA nucleotides.
Each nucleotide consists of a sugar, a phosphate group, and one of four nitrogenous bases.
The structure and orientation of the two strands are important to understanding DNA replication.

The new DNA strand that grows continuously in the 5' to 3' direction is called the

protist eukaryotes that are not plants, animals, or fungi ("misfits")

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.
