- How does DNA replication occur in a precise manner to ensure that identical genetic information is put into the new chromatid? See Figures 8.12 and 8.13. FIGURE 8.12 In DNA replication, the two polynucleotide strands uncoil, and each is a template for synthesizing a new strand. A replicated DNA molecule contains one new strand and one old strand. This mechanism is called semiconservative replication. FIGURE 8.13 A close-up look at the process of DNA replication. (a) As the strands uncoil, bases are added to the newly synthesized strand by complementary base pairing with bases in the template strand. The new bases are linked together by DNA polymerase. (b) DNA synthesis can proceed only in the 5 3 direction; newly synthesized DNA on one template strand is made in short segments and linked together by the enzyme DNA ligase.arrow_forwardIn 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 DNAarrow_forwardWhat proteins are crucial for creating and maintaining DNA replication forks? Choose the best explanation. Question 2 options: Helicase creates the replication fork; primase keeps the single strands from closing shut. Helicase creates the replication fork; single-strand binding proteins keep the single strands from reuniting. Ligase creates the replication fork; DNA polymerase II keeps the single strands from reuniting. Helicase creates the replication fork; ligase keeps the single strands from closing shut.arrow_forward
- In eukaryotes, the DNA replication rate is 50 nucleotides per second. How long would the replication of a chromosome of 150 million base pairs take if eukaryotic chromosomes were replicated like those of prokaryotes? Actually, eukaryotic replication takes only several hours. How do eukaryotes achieve this high rate?arrow_forwardIf the rate of replication in a particular prokaryote is 900 nucleotides per second, how long would it take 1.2 million base pair genomes to make two copies?arrow_forwardShows an autoradiograph of a replicating bacterial chromosome.

- Which of the following cis-elements in a bacterial origin of replication is where the parental DNA strands first separate when the DNA is bent?Question 30 options: A) GATC sequences B) DnaA box C) AT-rich regionarrow_forwardAfter 3 rounds of replication, what percent of the DNA molecules will contain only 15N? You take a sample of bacteria with DNA that contains only 14N and allow them to replicate in a medium that contains only 15N. After 3 rounds of replication, what percent of the DNA molecules will contain only 15N? Enter your answer as a whole number without the percent sign. For example, 5% would be entered as 5 and 37% would be entered as 37.arrow_forwardA region of DNA has six copies of a trinucleotide repeat. During one round of replication, the template strand slips as shown in the diagram. How many repeats will the DNA have if the newly synthesized strand is used as a template in the next round of replication? 1 5'-CAG 3'-GTC GTC 4 2 GTCH 3 2 CAG CAG GTC 3 GTC 5 4 CAG-3' GTC -5' 6 Next round of DNA replicationarrow_forward
- A researcher would like to introduce a foreign gene to bacteria and inserts the gene sequence into a circular DNA fragment. He was surprised to find out that the bacterial colony does not express the gene and realized that he did not introduce an origin of replication to the circular DNA. Although gene was introduced to the bacteria, why did not it express the gene?arrow_forwardWhat would the chromosome on the picture below look like after DNA replication?arrow_forwardBelow is a diagram of DNA replication as currently believed to occur in E. coli. Arrows start from numbers and end at specific points. Answer the questions relating to the locations specified by the numbers (1) Which end (5' or 3') of the molecule is here? (2) Which enzyme is probably functioning here to deal with supercoils in the DNA? (3) Which enzyme is probably functioning here to unwind the DNA?arrow_forward
