The correct answer is: C) the place where the parent DNA becomes unzipped during DNA replication is called the replication fork.
DNA Polymerase doesn't build DNA from scratch, rather it adds the correct nucleotides to the complementary parent strand.
DNA Polymerase adds nucleotides in the 5' to 3' direction, not the 3' to 5' direction.
DNA is made semiconservatively, meaning that there is a template strand from the parent DNA with a complementary strand being the new daughter strand.
The strand that is made continuously is the leading strand. The lagging strand is not made continuously, as it requires the use of Okazaki fragments.
Answer:
The carboxyl group, the amino group, and the central carbon
Explanation:
Answer:
Nucleus: The nucleus controls everything which takes place in the cell. It does this as it is the site of the cell's DNA. DNA contains the genetic code which is translated into proteins.

Answer:
The case in which facilitated diffusion would be needed is in the transport of large non-polar molecules moving down the concentration gradient.
Explanation:
Facilitated diffusion (FD) involves a form of passive transport, that is, it does not require energy and mobilizes substances across the cell membrane in favor of a concentration gradient.
The passive transport mechanism of FD is necessary only in the case of transport of very large molecules or polar molecules that:
- Cannot be transported by simple diffusion, due to the selective permeability of the membrane
- They follow a concentration gradient, from the place with the highest concentration to the one with the lowest concentration.
For FD to occur, it requires the use of a protein, which acts as a carrier of the molecules to be mobilized.
The other options are not correct because:
<em> A and C. Passive transport, as facilited diffusion, implies movement in favor of a concentration gradient.</em>
<em> B and C. Non-polar small or very small molecules can cross the membrane by simple diffusion.</em>
