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.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.Because each daughter DNA molecule comprises one of the parental strands and one newly created strand, this process is known as semiconservative replication. DNA replication makes sure that each daughter cell receives a complete and exact copy of the genetic material, which is necessary for the maintenance of genetic information throughout cell ... A. has a single origin of replication. B. does not produce a replication bubble. C. occurs only at a single replication fork. D. does not produce Okazaki fragments. E. All of these choices are correct. A. has a single origin of replication. The enzyme responsible for replacing RNA primers with DNA is a type of: DNA replication steps. 1) Helicase- unwinds the parental double helix. 2) DNA topoisomerase - upstream of helices alleviating torsional strain. 3) Single-strand binding proteins (SSBP) stabilize unwound DNA, aided by DNA gyrase (topoisomerase). 4) Primase synthesizes a short RNA primer for DNA polymerase to bind to in the 5' to 3' direction to ...It copies the information for reproduction from RNA back into DNA. Study with Quizlet and memorize flashcards containing terms like What would be the result of a cytosine base being substituted for a thymine base in a DNA segment during DNA replication?, Which statement is the first step of protein synthesis?, Which statement is true? and more.Step 9. The new strand is proofread to make sure there are no mistakes in the new DNA sequence. Step 10. Finally, an enzyme called DNA ligase seals up the sequence of DNA into two continuous double strands. Step 11. The result of DNA replication is two DNA molecules consisting of one new and one old chain of nucleotides.Study with Quizlet and memorize flashcards containing terms like Classify each item according to its role in DNA replication., Match each enzyme with its function in E. coli., If 28% of the DNA nucleotides from a certain organism contain the base T, what percent will contain the base G? and more.Study with Quizlet and memorize flashcards containing terms like DNA replication is the process by which DNA is (blank) during the cell cycle., DNA replication takes places in the (blank) of a eukaryotic cell., DNA is replicated during the (blank) of the cell cycle. and more.3) c. 4) d. The process of DNA replication results in a copy of the original DNA molecule. true. DNA does not have to break apart to be copied. false.

An enzyme called helicase unwinds the DNA by breaking the hydrogen bonds between the nitrogenous base pairs. replication forks. As the DNA opens up, Y-shaped structures called replication forks are formed.Arrange these events in the correct order: a. DNA polymerase adds nucleotides in the 5' to 3' direction. b. Replication form is formed. c. DNA polymerase attaches to the RNA primer. d. Okizaki fragments are bound together by ligase. e: DNA helicase unwinds DNA. Terms in this set (20) Explain what the term semiconservative means with respect to DNA replication. The 2 DNA molecules created through replication, each contain one of the original strands paired with a newly synthesized strand. Because half of the original molecule is conserved in each molecule, replication is said to be semiconservative.Study with Quizlet and memorize flashcards containing terms like Which of the following components are required for DNA replication in prokaryotes?
