One strand of a single DNA helix is labeled red while the other strand of the same DNA helix is labeled blue. This double helix DNA is replicated through the process of semi-conservative replication. Note that a completely newly synthesized strand of DNA will be white. After three rounds of DNA replication, how many all-white DNA (both strands are white) will there be? Explain your reasoning.
What 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.
There are 6 parts to this question: This is a follow up to the prior question regarding
the replication of the DNA strand below.
The DNA strand is here for your reference and you do not need to do anything with or
to it.

c) what enzyme separated the parental DNA template strands,
d) what bonds were broken?
e) what enzyme replicates DNA
f) before DNA can be replicated/copied, what must be laid down to allow the enzyme
in "e" to replicated the DNA (be specific)?
g) our DNA is replicated in many "pieces", what enzyme connects these many "pieces"
into one continuous DNA strand that becomes the sister chromatid?
h) during what specific phase of the cell cycle does this DNA replication process
occur? (This should be a review question from last topics we covered).

- DNA replication is called semi- conservative because of the two new strands of DNA is old DNA from the original DNA molecule and is new DNA. Answers to choose from: 1) Half 2) All 3) Nonearrow_forwardThe template (antisense) strands of two complete (double-stranded) DNA molecules have the base sequences shown in the table below. Two replication experiments are done with each molecule: 1. In Experiment #1, samples of each DNA molecule are incubated with radioactive adenine, along with appropriate replication enzymes, ATP, adenine, thymine, and cytosine. Experiment #1 is stopped when each DNA molecule has replicated once. 2. In Experiment #2, all the DNA molecules from #1 are purified, and then incubated with with a similar reaction mixture - except non-radioactive adenine is used this time. Experiment #2 is stopped when each DNA molecule has replicated one more time. Predict the percentage of DNA in each sample that is radioactive after each experiment.

What will be the most likely consequence of this mutation? The DNA would not exist in a supercoiled state. There would be no RNA primers laid down. The DNA will not be able to unwind to initiate replication. The DNA strands would contain pieces of RNA.
