DNA Nature & Replication Crossword Puzzle

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.
