QUESTIONS LIST:

  • 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.
