nucleotides:  These basic units of nuclei acids are composed of a pentose sugar, a phosphate group and a nitrogenous base.
pyrimidines:  Cytosine, thymine and uracil belong to this group.
purines:  Adenine and guanine belong to this group.
complementary:  This describes the nitrogenous base pairs:   A–T  &  G–C.
two:  Adenine and thymine join with this number of hydrogen bonds.
three: Cytosine and guanine join with this number of hydrogen bonds.
double helix: This describes the structural form of DNA.
chromosomes:  There are 46 (23 pairs) of these in every human body cell.
self-replication:  DNA is capable of this.
hereditary: DNA stores this kind of information.
controls:  DNA indirectly does this for the functioning of all living things.
phenotypic:  This describes a physical trait that is coded for by a gene(s).
genotypic:  This describes the genetic make-up that codes for specific physical traits.
allele:  This is a variation or option for a gene.
gene pool:  This is (collectively) all the genes of an interbreeding group (species).
DNA helicases:  These enzymes are involved in the first stage of DNA replication.
unzipping:  This is the first stage of DNA replication.
complementary base:  This pairing process is the second stage of DNA replication.
template:  Each old strand of nucleotides serves as this for the making of each new DNA strand.
DNA polymerases:  These enzymes are involved in the final stage of DNA replication.
adjacent nucleotides: These join together in the final stage of DNA replication.
sugar-phosphate:  This backbone results when covalent bonds form between the sugar and phosphates of adjacent nucleotides.
semi-conservative: When DNA replication is complete, each new DNA strand contains an original parent strand and a new strand.  What is this type of replication called?
DNA:  This is the genetic material of a cell.
histones:  Each DNA chromatid coils around these protein nodules as a cell begins its division process.
