Course Contents. Homework 9 1 (20 pts) TimerNotes Evaluate True or false? True The trombone model describes the lengthening of the loop formed by the leading strand during replication. rue Transcription factors (DNA binding proteins) recognize sequences by binding the major and minor grooves of the double helix. False Hoogsteen hydrogen bonding is found in quadroplex DNA. False The shorthand notation pApCpG denotes that a phosphate is attached to the 3' of the guanine nucleotide unit True -The Klenow fragment is an E. coli DNA polymerase fragment True Histone protein side chains are heavily modified to regulate tight binding to the phosphate backbone of DNA. False The polymerization of DNA is essentially irreversible due to the hydrolysis of pyrophosphate False RNA polymerase requires a primer for initiation. True The key Tyr at position of 766 of DNA Pol I facilitates watson-Crick pairing through electrostatic interactions with the incoming base. True The Okazaki fragment has exonuclease activity. True A-form DNA is shorter than the B-form per turn due in part to the decreased pitch of the helices. rue v n the ligase reaction a Lysine in the enzyme is adenylated, thus allowing the free DNA phosphate to attack and acquire the adenylation and create a high energy bond. False The basic amino acids the line the pocket of DNA Pol I promotes interactions with the acidic nature of the DNA phosphate backbone. False The DNA strand that is replicated continuously is known as the lagging strand. True The ß subunits of E coli DNA polymerase form a sliding clamp that surrounds the DNA strands at the replication fork. True ? | Z-DNA is a right-handed helix that is longer than B-DNA per turn ue During prokaryotic replication, helicase utilizes ATP to power strand separation. FalseA molecule composed exclusively of a nitrogen-containing aromatic base attached to a phosphorylated ribose is a nucleoside. False The process of rehybridizing melted DNA is called denaturation True The replication of DNA is semiconservative because one strand of parental DNA is retained in each daughter DNA Submit Answer Tries 0/99 Post DiscussionExplanation / Answer
