DNA/Ecology (Ecology, DNA, DNA (Deoxyribonucleic Acid) is composed of two Polynucleotide Strands (the polymers of nucleotides), which form what looks like a ladder. The Nitrogenous Bases in DNA store the instructions for making polypeptide chains, essentially coding for every feature of the entire organism., blueprint of life (has the instructions for making an organism)

made of repeating subunits called nucleotides, DNA is the genetic material, and genes are made of DNA. DNA therefore has two essential functions: replication and expression.
Replication means that the DNA, with all its genes, must be copied every time a cell divides.
Expression means that the genes on DNA must control characteristics. A gene is a section of DNA that codes for a particular protein. Characteristics are controlled by genes through the proteins they code for)
