When DNA replication occurs, the DNA strand is being unwound, causing the DNA to be overwound tightly past the replication fork.
For example, If you have ever wrapped two strings around each other and then tried to pull part the middle of the string while holding the ends tight, the rest of the string past the place you're pulling the string apart becomes very tight and strained.
Topoisomerase is an enzyme that binds to the DNA and helps release some of that strain by unwinding the DNA past the replication fork.
That means the correct box is the leftmost one. Hope this helps:)
Answer;
Forward chaining and backward chaining are Similar in that;
Both are used to teach a chain of behaviors.
Both use procedures,
Both teach one behavior at a time and chain the behaviors together.
Both procedures use prompting and fading to teach each component
Explanation;
-Backward chaining; When you teach the last stimulus-response component first. Then teach the next to last component and so on.
-Forward chaining; Teach the first stimulus-response component first. Then teach the second component and so on
Animal cells have plasma membrane while plant cells have
cell wall and cell membrane.
A plant cell has 1 large vacuole while an animal cell has
more than 1 vacuole which is smaller compared to the vacuoles of a plant cell.
The vacuole of a plant cell is hypertonic because it takes up to 90% of the
cells volume.
A plant cell has chlorophyll or chloroplasts (which gives
colors to plants), animal cells does not have chloroplasts.
Cell division is also called mitosis (this term is used for
both animal and plant cells, no difference on that). For plant cells,
centrifugal division occurs, its starts in the middle going outwards creating
the cell plate. For animal cells, division is centripetal that it comes from
the outside going toward the center and that is called the cleavage furrow.
