What are the products of semiconservative replication for a double-
stranded DNA molecule? - ANSWER ✓✓✓Two double-stranded
DNA molecules, each consisting of one parental strand and one
daughter strand. Why is DNA replication essential for a cell? -
ANSWER ✓✓✓An organism must copy its DNA to pass genetic
information to its offspring. What is the function of the parental
DNA in replication? - ANSWER ✓✓✓It serves as the template for
DNA replication. Which enzyme breaks the hydrogen bonds during
replication? Replication fork Stabilizing proteins DNA helicase ATP
- ANSWER ✓✓✓DNA Helicase How do stabilizing proteins work on
the DNA? They bind to the single-stranded DNA. They bind to the
, double-stranded DNA. They form the replication fork. They use
ATP to break the hydrogen bonds - ANSWER ✓✓✓They bind to
single-stranded DNA. In which direction does the replication fork
move? - ANSWER ✓✓✓It moves ahead of the newly synthesized
DNA. What ensures that the single strands of DNA do not come
back together? ATP DNA helicase Stabilizing proteins The
replication fork - ANSWER ✓✓✓Stabilizing proteins What
characteristic of DNA allows two connected DNA polymerases to
synthesize both the leading and lagging strands? DNA is flexible.
DNA is double-stranded. DNA has a helical shape. DNA is
antiparallel. - ANSWER ✓✓✓DNA is flexible What is the function
of connector proteins? - ANSWER ✓✓✓They link the leading
strand DNA polymerase and the lagging strand DNA polymerase
together. Which DNA strand is synthesized continuously? Lagging
strand Neither the leading nor the lagging strand is synthesized
continuously. The leading and lagging strands are both synthesized
continuously. Leading strand - ANSWER ✓✓✓Leading strand.
Which of the following are terms associated with Okazaki
fragments? Discontinuous DNA ligase Lagging strand Lagging
strand, DNA ligase, and discontinuous - ANSWER ✓✓✓Lagging
strand, DNA ligase, and discontinuous Why is the DNA synthesis of
the lagging strand considered discontinuous? - ANSWER ✓✓✓The
synthesis is moving in the opposite direction from the replication
fork. Stages in which the lagging strand is synthesized: - ANSWER
✓✓✓1. DNA polymerase begins synthesizing the lagging strand by
adding nucleotides to a short segment of RNA. 2. After each strand
of the lagging strand is complete, it is released from the DNA
polymerase. 3. A different DNA polymerase replaces the RNA
segments with DNA. 4. DNA ligase seals the gaps between the
pieces, and eventually forms a continuous strand. In DNA
replication, which nucleotides would pair up with the following
nucleotides? A C G - ANSWER ✓✓✓A ---- T C ---- G G ---- C
