Molecular Diagnostics Chapter 1 Exam 100% solved

Molecular Diagnostics Chapter 1 Exam 100% solved trait - ANSWERparticular characteristic Which elements make up the macromolecule of DNA? - ANSWERcarbon, nitrogen, oxygen, phosphorous, and hydrogen What is the structure of DNA? - ANSWERphosphorylated ribose sugar (deoxy ribose) backbone with a nitrogenous base (guanine, adenine, cytosine, thymine) two strands joined together through hydrogen bonds form a double helix What type of bond joins two nucleotides? - ANSWERphosphodiester bond nucleotide - ANSWERa nucleic acid with a phosphorylated ribose sugar and a nitrogen base, triphosphate nuclein - ANSWERviscous substance isolated from nuclei, discovered by Miescher and later found to be DNA nitrogen base - ANSWERa carbon-nitrogen ring structure that is part of a nucleoside deoxyribose - ANSWERribose without a hydroxyl group on the carbon in position 2 on the sugar ring, with a hydroxyl group on the third carbon which is important for phosphodester bond formation The. sequence is the ________ of nucleotides. - ANSWERorder nucleoside - ANSWERribose sugar (unphosphorylated sugar) + nitrogenous base, adenosine, guanosine, cytidine, thymidine purine - ANSWERadenine, guanine (think Ag gold is pure, still has ring formation) double ring structure pyrimidine - ANSWERcytosine, uracil, thymine (think CUT, ring structure has been "cut") single-ring Does adenine thymine pairing or cytosine guanine pairing have three hydrogen bonds? - ANSWERcytosine + guanine (think c&g closer in alphabet, closer in space) Which carbon on the deoxy ribose sugar forms a phosphodiester bond? Which catbon is the phosphate group attached to? What is this process called? - ANSWERthe third carbon, the fifth carbon, DNA polymerization What is the difference between B-form, A-form, and Z-form DNA? - ANSWERB- hydrated, 10.5 steps, right ha
