Which of the following regarding DNA replication is FALSE.Replication of DNA is highly regulated.DNA is the only biomolecule that can be replicated.Replication is an amazingly complex process: it is amazing that can occur in aphysiologically relevant time frame.The fact that DNA can be replicated allows it to serve as the genetic material.The progeny receive one strand that originated from the parent and one newlysynthesized strand.

There are four classes of biological macromolecules: Nucleic acids, proteins, lipids and…

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.
DNA replication is called semi-conservative because ___ (all, all or none) of the two new strands of DNA is old DNA from the original DNA molecule and ___ (all, all or none) is new DNA.
Fill in the blank with the most appropriate term that is described by the following statement: Synthesizes a short RNA primer molecule necessary for DNA replication
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
DNA polymerase occasionally incorporates the wrong nucleotide during DNA replication. If left unrepaired, the base-pair mismatch that results will lead to mutation in the next replication. As part of a template strand, the incorporated wrong base will direct the incorporation of a base complementary to itself, so the bases on both strands of the DNA at that position will now be different from what they were before the mismatch event. The MER-minus strain of yeast does not have a functional mismatch excision repair system, but it has normal base excision repair and nucleotide excision repair systems. Which of the following statements is correct about differences in the mutation spectrum between MER-minus and wildtype yeast? More than one answer is correct. Options: More point mutations will arise in MER-minus yeast. Fewer point mutations will arise in MER-minus yeast as compared with wildtype. Of the total point mutations that…
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
DNA replication is semi-conservative; a copy of each strand is made and the new set is inherited to one cell and the old set is inherited to the second cell. True False
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 is/are TRUE for DNA Replication? Two daughter DNAs are formed, each one contains an old and new strands. When the (parent) DNA strands unwind, the 3'→ 5' strand is the leading strand while the 5'→3' strand is the lagging strand. Requires dATP, dTTP, dGTP, dCTP and Mg2+ The replisome is the biological machine responsible in replicating DNA.
In eukaryotes, replication starts more or less simultaneously at multiple points of origin along a chromosome. What pattern of radioactivity would be found after briefly exposing to radioactive adenine a cell that is just beginning to replicate, and then quickly replacing the radioactive with nonradioactive adenine? many short sections of radioactive DNA one radioactive section of DNA starting at one particular end of the chromosomes many short radioactive strands of DNA in the leading strands only many short radioactive sections of DNA in the lagging strands only no radioactive sections in the DNA
Replication of nuclear DNA begins at the Ori (origin of replication). True or false
How is bacterial DNA replication different from eukaryotic DNA replication? Multiple Choice The result of bacterial DNA replication is two new double stranded DNA molecules that each contain a template strand and a newly synthesized strand, while the result of eukaryotic DNA replication is one newly synthesized double stranded DNA molecule and one DNA molecule that was the original template. Bacterial DNA replication involves nucleotides that are not found in eukaryotic DNA replication. Bacterial DNA replication moves out from the origin of replication in two directions, while eukaryotic DNA replication moves out from the origin of replication in only one direction. Bacterial DNA replication only replicates small pieces of the chromosome, while eukaryotic DNA replication replicates the entire chromosome. Bacterial DNA replication begins at a single location on the chromosome, while eukaryotic DNA replication begins in many places dispersed throughout each…
