120929914CytosineOne of four nitrogen-containing bases in the nucleotides composing the structure of DNA and RNA; pairs with guanine.3
120929915DNA (deoxyribonucleic acid)Nucleic acid polymer produced form covalent bonding of nucleotide monomers that contain the sugar deoxyribose; the genetic4
120929916DNA polymeraseDuring replication, and enzyme that joins the nucleotides complementary to a DNA template5
120929917DNA repair enzymeOne of several enzymes tat restore the original base sequence I n an altered DNA strand6
120929918DNA replicationSynthesis of a new DNA double helix prior to mitosis and meiosis in eukaryotic cells and during prokaryotic fission in prokaryotic cells.7
120929919Genetic mutationAltered gen whos e sequence of bases differes form the previouls sequence.8
120929920GuanineOne of four nitrogen-containing bases in nucleotides composing the structure of DNA and RNA; pairs with cytosine.9
120929921Nucleic acidPolymer of nucleotides; both DNA and RNA are nucleic acids10
120929922NucleotideMonomer of DNA and RNA consisting of a 5-carbon sugar bonded to a nitrogenous base and a phosphate group11
120929923ProofreadingProcess used to check the accuracy of DNA replication as it occurs and to replace a mispaired base with the rights one12
120929924PurineType of nitrogen-containing base, such as adenine and guanine, having a double-ring structure13
120929925PyrimdineType of nitrogen-containing base such as cytosine, thymine, and uracil, having a single-ring structure14
120929926Replication forkIn eukaryotes, the point where the two parental DNA strands separate to allow replication15
120929927RNA (ribonucleic acid)Nucleic acd produced rform covalent bonding of nucleotide monomers that contain the sugar ribose; occurs in three forms: messenger RNA, ribosomal RNA, and transfer RNA.16
120929928Semiconservative replicationDuplication of DNA resulting into two double helix molecules each having one parental an one new strand17
120929929TemplateParental strand of DNA that serves a a guide for the complementary daughter strand produced during DNA replication.18
