What Is The function Of DNA Polymerase III? A) come Unwind The DNA Helix during ReplicationB) come Seal together The broken Ends that DNA StrandsC) To include Nucleotides to The finish Of A cultivation DNA StrandD) to Degrade Damaged DNA MoleculesE) come Rejoin The two DNA Strands (one new And One Old) after Replication
Start studying for the Molecular device of DNA replication for Midterm and also for animal physiology and evolution through our easy and simple quiz-based flashcard quizzes. Learn key terms, vocabulary, and also definitions, and much an ext of the Molecular device of DNA replication with the help of our flashcards quizzes through ease.
What is the role of DNA polymerase III? A) to unwind the DNA helix throughout replication B) to seal with each other the damaged ends that DNA strands C) to add nucleotides to the end of a cultivation DNA strand D) to degrade damaged DNA molecules E) to rejoin the two DNA strands (one new and one old) ~ replication
You briefly expose bacteria experience DNA replication to radioactively labeled nucleotides. As soon as you centrifuge the DNA isolated from the bacteria, the DNA separates into two classes. One class of labeled DNA includes very huge molecules (thousands or even millions that nucleotides long), and also the various other includes quick stretches of DNA (several hundred to a few thousand nucleotides in length). These two classes that DNA probably represent A) top strands and also Okazaki fragments. B) lagging strands and Okazaki fragments. C) Okazaki fragments and also RNA primers. D) leading strands and also RNA primers. E) RNA primers and mitochondrial DNA.
Hich of the following clears the RNA nucleotides indigenous the primer and also adds identical DNA nucleotides come the 3" finish of Okazaki fragments? A) helicase B) DNA polymerase III C) ligase D) DNA polymerase ns E) primase
Which that the adhering to separates the DNA strands during replication? A) helicasa B) DNA polymerase II C) ligase D) DNA polymerase H E) primase
Which of the following covalently connects segment of DNA? A) helicase B) DNA polymerase III C) ligase D) DNA polymerase i E) primasa
Which of the following synthesies short segments that RNA? A) helicase B) DNA polymerase III C) ligase D) DNA polymerase ns E) primase
The difference between ATP and also the nucleoside triphosphates used during DNA synthetic is that A) the nucleoside triphosphates have actually the street deoxyribose; ATP has the sugar ribose. B) the nucleoside triphosphates have two phosphate groups; ATP has three phosphate groups. C) ATP includes three high-energy bonds; the nucleoside triphosphates have two. D) ATP is uncovered only in human being cells; the nucleoside triphosphates are uncovered in every animaland tree cells. E) tree phosphate monomers are active in the nucleoside triphosphates, yet not in ATP
The leading and also the lagging strands different in the A) the leading strand is synthesized in the very same direction together the activity of the replication fork, and the lagginc strand is synthesized in the opposhte direction. B) dhe top strand is synthe3ized by including nucleotides come the 3" finish of the growing strajd, and the lagging strand is synthesized by including nucleotides to the 5" end. C) the lagging strand is synthesized continuously, whereas the top strand is synthesized in brief fragments the are eventually stitched together. D) the leading strand is synthesized at twice the price of the lagging strand.
Which the the following ideal describes the enhancement of nucleotides to a farming DNA chain? A) A nucleoside triphosphate is included to the 5" end of the DNA, publication a molecule the pyrophosphate. B) A nucleoside triphosphate is included to the 3" end of the DNA, release a molecule the pyrophosphate. C) A nucleoside diphosphate is included to the 5" finish of the DNA, publication a molecule of phosphate. D) A nucleoside diphosphate is included to the 3" finish of the DNA, release a molecule that phosphate. E) A nucleoside monophosphate is added to the 5" end of the DNA.
A brand-new DNA strand elongates only in the 5" come 3" direction due to the fact that A) DNA polymerase begins including nucleotides at the 5" finish of the template. B) Okazaki pieces prevent elongation in the 3" come 5" direction. C) the polarity of the DNA molecule prevents enhancement of nucleotides in ~ the 3" end. D) replication have to progress towards the replication fork. E) DNA polymerase can only add nucleotides to the cost-free 3" end.
What is the function of topoisomerase? A) relieving stress, overload in the DNA ahead of the replication fork B) elongation of brand-new DNA at a replication fork by enhancement of nucleotides to the currently chain C) the addition of methyl groups to bases the DNA D) unwinding of the double helix E) stabilizing single-stranded DNA at the replication fork
What is the function of DNA ligase in the elongation of the lagging strand throughout DNA replication? A) synthesize RNA nucleotides to do a primer B) catalyze the lengthening of telomeres C) join Okazaki pieces together D) unwind the parental twin helix E) stabilize the unwound parental DNA
Which of the following aid to organize the DNA strands apart if they room being replicated? A) primase B) ligase C) DNA polymerase D) single-strand binding proteins E) exonuclease
Individuals with the disorder xeroderma pigmentosum space hypersensitive come sunlight. This occurs because their cells have which impaired ability? A) They cannot replicate DNA. B) They can not undergo mitosis. C) They can not exchange DNA with other cells. D) They can not repair thymine dimers. E) They carry out not recombine homologous chromosomes during meiosis.
