UNIT IV STUDY GUIDE -Deoxyribose(sugar)nucleic Acid – DNA – pentose sugar; generic material of nearly all organisms - Haploid – cell condition in which only one type of chromosome is present. - Nucleotid e – monomer of DNA and RNA consisting of 5-carbon sugar bonded to a nitrogenous base and a phosphate group. - Cytosine (C): one of four nitrogen-containing bases making up DNA and RNA; pairs with guanine. -Guanine (G): one of four nitrogen bases of DNA, pairs with cytosine. (purine) - Adenine (A): one of four nitrogen bases of DNA. (purine) - Thymine (T): one of four nitrogen bases of DNA. (Pyriamadine) - Purine: type of nitrogen containing base; such as adenine and Guanine; has double-ring structure. -pyrimadine: nitrogen containing base, has single ring structure; (cytosine, thymine) - single strand: base bonded by sugar phosphate bonds; covalent bond - double strand: two single strands bounded base to base; hydrogen bond. Double helix - base pairing: pyrimidine bonds to purine; (A to T) and (G to C) - semiconservative : duplication of DNA resulting in two double helix molecules, each having one parental and one new strand. -DNA Polymerase : during replication, an enzyme that joins the nucleotides in the DNA form. - DNA Ligase : enzyme that links DNA fragments; used during production of recombinant DNA to join foreign DNA to vector DNA. -RNA polymerase
