A replication unit is any chunk of DNA that is capable of being replicated — e.g. a plasmid with an origin of replication (ORI) is a replication unit. Alternatively, this can also mean a region of DNA that is replicated together.Study with Quizlet and memorize flashcards containing terms like What is the first thing to occur in DNA replication? A., the strands of the DNA double helix are separated B., the synthesis of a short RNA primer C., the extension of DNA from the 3′ end of the RNA primer D., the removal of the RNA primer, which is replaced by DNA, Which of the strands use a …1. Helicases bind to replication origins and separate the two strands of DNA, While Topoisomerase relieves stress on the strand downstream. 2. Primase attaches a short RNA primer to the template strand of DNA. 3. DNA polymerase III attaches a new nucleotide to the 3' end of the RNA primer, fills in DNA (strand grows in the 5' to 3' direction) 4. Show details DNA Replication As discussed in Chapter 3, DNA replication is a semiconservative process in which each parental strand serves as a template for the …Study with Quizlet and memorize flashcards containing terms like When we say that DNA replication is semiconservative, we mean that: -None of the other answer options is correct. -only half of an organism's DNA is replicated during each cell division. -when DNA is replicated, each new double helix contains one parental strand and one newly synthesized daughter strand. -parental DNA stays in ...Which of the following are differences between prokaryotic and eukaryotic DNA replication? - Prokaryotes produce more than 2 daughter molecules per parent molecule - The prokaryotic genome is replicated much faster than the eukaryotic genome - Only eukaryotic cells display semiconservative replication - Prokaryotes have only one origin of …Study with Quizlet and memorize flashcards containing terms like Which event may occur in all viruses, prokaryotes, and eukaryotes? a. duplication b. aneuploidy c. translocation d. mutation e. none of these, The difference between normal and sickle-cell hemoglobin is based upon a. the number of amino acids in the molecule. b. the substitution of one …The first stage of DNA replication in prokaryotes is the uncoiliing of the DNA double helix by the enzyme helicase. Helicase seperataes the DNA into two template strands. RNA primase then adds a short sequence of RNA to the template strands. This short sequence of RNA is a primer which allows DNA polymerase III to bind to the strands and start ...Click the card to flip 👆. What is the structure of DNA? What is the building block of DNA? What is the compliment nitrogenous base to adenine? Uracil & Thymine. When in the cell cycle does DNA Replication occur? How many replication forks are in the replication bubble? sonoranie_toadie. Giovanni_Spinelli.Study with Quizlet and memorize flashcards containing terms like Which is more reactive, RNA or DNA?, _____ proteins must possess a 2 fold axis of symmetry., What are the 4 families of DNA binding proteins? and more.Study with Quizlet and memorize flashcards containing terms like DNA replication is similar/different in prokaryotes and eukaryotes., DNA replication is a(n) catabolic/anabolic polymerization process., DNA replication requires _____ and _____ and more. Study with Quizlet and memorize flashcards containing terms like When _____ form after an exposure to ultraviolet (UV) light, a _____ can remove the damaged nucleotides and replace them with normal nucleotides., What is the major difference between bacterial chromosomes and eukaryotic chromosomes, The role of DNA polymerases in DNA replication is to _____. and more.Here's an interesting 'DNA replication quiz' that is designed to test your knowledge about the DNA replication process. Think you know everything about the …Okazaki fragments. Small fragments of DNA produced on the lagging strand during DNA replication, joined later by DNA ligase to form a complete strand. Telomerase. An enzyme that catalyzes the lengthening of telomeres. The enzyme includes a molecule of RNA that serves as a template for new telomere segments. Telomere.Explain the semi-conservative process of DNA replication. DNA helicase breaks the hydrogen bonds between the base pairs, causing the double helix structure to unwind. Free nucleotides bind their bases to their complementary base pair on the exposed polynucleotide. Condensation reactions using DNA polymerase join the nucleotides, …Study with Quizlet and memorize flashcards containing terms like 1st) unwinds a segment of DNA and breaks the hydrogen bonds between the 2 complimentary strands of DNA, 1b) The ____react with and stabilize the separated, single stranded section of DNA molecule, 2nd) The enzyme complex_____ engages the separated portion of the molecule and initiates …after DNA replication is complete, a single nucleotide is removed and replaced in the newly synthesized DNA strand. Telomerase. an enzyme with a built-in RNA template that extends the ends of chromosomes by copying the RNA template and extending one end of the chromosome. telomeres. the ends of linear chromosomes where the sequences appear …Study with Quizlet and memorize flashcards containing terms like DNA replication is similar/different in prokaryotes and eukaryotes., DNA replication is a(n) catabolic/anabolic polymerization process., DNA replication requires _____ and _____ and more.Okazaki fragments.
