Which of the comparisons between DNA polymerase and RNA polymerase is false? -Both DNA polymerase and RNA polymerase have proofreading activity. -DNA polymerase requires an additional enzyme to unwind double-stranded DNA molecules, but RNA polymerase does not. -Both DNA and RNA polymerase catalyze the addition of nucleotides to the 3’ end. -DNA polymerase needs a free 3’-OH to begin the polymerization reaction, but RNA polymerase does not.

Semi-conservative replication means (a) when DNA is replicated it consists one old strand and one new strand   (b) the strands are anti-parallel   (c) the strands are complementary   (d) A=T, G=C   (e) none of the above

If you had a mixture of single-stranded DNA fragments, all 4 deoxyribonucleoside triphosphates, and DNA polymerase III. Would the single-stranded DNA fragments be able to be replicated? No, DNA polymerase I is needed No, ribonucleoside triphosphates are needed Yes, DNA polymerase III would be able to copy the DNA fragments from the 3' to 5' end by attaching the complementary deoxyribonucleosides No, DNA polymerase III would not be able to bind to the DNA fragment to start replication

During the polymerase chain reaction, heat is used to   Question 26 options:   break covalent bonds   accelerate chemical processes   anneal DNA primers to single-stranded DNA   allow the synthesis of new DNA strands in the 5' to 3' direction from the primers   break hydrogen bonds

When DNA replication was investigated by using heavy, N15 DNA to mark the original molecules, and light, N14 DNA to mark the newly synthesized molecules, one band was found in the middle of the centrifuge column after one round of replication, and two bands were found (middle and top of column) after 2 rounds of replication. Imagine that after 1 round of replication 2 bands were found, one at the bottom and one at the top of the centrifuge column. In that case, what model of DNA replication would have been supported?     The dispersive model     The conservative model     The Franklin model     The semi-conservative model

What is the role of DNA polymerase in DNA replication? O A. DNA polymerase replicates tRNA, mRNA and rRNA B. DNA polymerase adds A-U-G-C as compliments to the original DNA strand to make an identical copy. O C. DNA polymerase "unzips" the DNA D. DNA polymerase adds complimentary free nucleotides to the original strand to make and identical copy. Submit Clear form Never submit passwords through Google Forms.

The following diagram represents a DNA molecule that is undergoing replication. Draw in the strands of newly synthesized DNA and identify (a) the polarity of the newly synthesized strands, (b) the leading and lagging strands, (c) Okazaki fragments, and (d) RNA primers.

Which of the following statements about DNA replication is INCORRECT? Select one: O a. DNA polymerase is the enzyme that adds nucleotides to the growing DNA strand. O b. DNA polymerase can only synthesize the new DNA strand in the 5' to 3' direction. O c. helicase is the enzyme which connects Okazaki fragments on the lagging strand. O d. the lagging strand has many primers. O e. the leading strand has only one primer.

The image below shows the replication bubble of a piece of DNA in the process of replication. However, the image only shows the DNA strands being replicated. Fill in the rest of the elements of the figure, specifically: primers, Okazaki fragments, newly replicated leading strand DNA, as well as the enzymes helicase, primase, DNA polymerase III, DNA polymerase I and ligase. Also be sure to indicate the 5’ and 3’ ends of all nucleic acid polymers.

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
