A cell containing a single chromosome is placed in a medium containing radioactive phosphate, making a new DNA strand formed by DNA replication radioactive. The cell replicates its DNA and divides. Then the daughter cells replicate their DNA and divide, resulting in a total of four cells. Sketch the DNA molecules in all four cells, showing a normal DNA strand as a solid line and a radioactive DNA strand as a dashed line.
DNA replication involves a series of steps, including initiation, making primers, extension, and connecting DNA fragments. The cell uses different enzymes in a particular order to accomplish these steps. Which of the following represents the correct general order of enzyme use? A. DNA polymerases, helicase, primase, ligase B. Helicase, ligase, primase, DNA polymerases C. Helicase, primase, DNA polymerases, ligase D. Primase, helicase, DNA polymerases, ligase
After 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.

- Which of the following statements BEST describes the process of DNA Replication? Group of answer choices The two strands of the parental molecule separate and serves as template for synthesis of a new strand. Each new strand is identical to its template strand. Each strand of both daughter molecules contains a mixture of old and newly synthesized DNA. The two parental strands reassociate after acting as templates for new strands restoring the parental double helix.arrow_forwardDraw replication forks that show what you would expect to see if a cell were unable to make the following enzymes: DNA Polymerase Helicase Primase Ligasearrow_forwardAfter the DNA is finished making a copy of itself, the chromosomes are in the shape of what letter of the alphabet – I or X?arrow_forward
- When chromatin is treated with non-specific nucleases, what is the length of the resulting pieces of DNAarrow_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_forwardPlace the following steps of DNA replication and repair in the correct order by numbering them from 1 to 5. a. A template strand begins to be replicated. b. If the incorrect base is not identified and replaced, it remains as a point mutation in the DNA. c. DNA polymerase identifies and replaces most incorrect bases with the correct base, complementary to the base on the template strand. d. An incorrect base is added to the growing strand of DNA. e. Proteins identify and replace any incorrect bases missed by DNA polymerase.arrow_forward
