In DNA replication, the fundamental reason that Okasaki fragments are produced is that Group of answer choices DNA replication can proceed only in the 5’ to 3’ direction replication on the leading strand is slower than replication on the lagging strand DNA polymerase tends to slip while replicating the lagging strand DNA polymerase has to alternate between the leading and lagging strands during replication none of these are true.
Bacterial and eukaryotic replication, have many similarities. Which of the following is not a true comparison? Group of answer choices Both form loops with the lagging strand template to accommodate the antiparallel nature of DNA. Both incorporate a sliding clamp mechanism in their replication polymerase. Both initiate replication with recognition of conserved sequences, where the DNA will first open up (using proteins) Both have a primer made only of ribonucleotides, and then exhibit polymerase switching to the replicative polymerase.
I'm a bit confused about this question will someone help me understand the concept
Medgie is creating his science fair project on DNA replication. His final display board shows the following. Human DNA Replication Steps Step 1 DNA unwinds in the nucleus Step 2 Complementary base pairs are deleted Step 3 DNA rewinds back together Step 4 The newly made DNA helix is placed in a cell formed in Mitosis According to Medgie's project, which of the following identifies and explains which of the steps is incorrect? O Step 4 is incorrect because not all human cells require DNA. O Step 3 is incorrect because the DNA remains unwound to be transcribed into RNA. Step 2 is incorrect because the complementary base pairs are used as a template, not deleted. Step 1 is incorrect because DNA doesn't unwind in the nucleus, instead it unwinds in the cytoplasm Previous
A drug that inhibits the DNAa protein is added to a culture of E. coli cells. What is the first step of DNA replication that will be impaired by this drug? Group of answer choices Keeping parent DNA strands separated Releasing tension generated by supercoiling Activating the origin of replication Making primers Forming phosphodiester bonds
What is the function of DNA polymerase in DNA replication? to create replication bubbles by unravelling the parental strands of DNA to insert new bases during elongation, using the parent strand as a template to create an RNA primer to initiate DNA replication to anneal (splice) smaller fragments of DNA to create one continuous strand O all of the above
Which of the following statements about the DNA double helix is FALSE? O The base pairs are located in the center of the helix O The plane of the base pairs is perpendicular to the direction of the deoxyribose- phosphate backbone O The two strands have the same 5' to 3' direction (i.e, are parallel) O The base pairs stack on one another O The deoxyribose-phosphate backbone is on the outside of the helix
