Which structure forms as DNA unwinds? A. a special marker B. a complementary base C. a replication bubble D. a double helix
kozerog [31]

A replication bubble forms as the DNA unwinds.

Option C  

<u>Explanation</u>:  

Replication bubble is the space where the strands of double helical DNA structure are separated with the help of DNA helicase. The strands of the double helical DNA are still in the helix form on the both end of the unwinded DNA stand which gives this region an appearance of a bubble.

DNA unwinding is the first step in replication or transcription of the DNA molecule. DNA helicase separates the two types of "DNA" that are connected by hydrogen bonds with the help of ATP hydrolysis.

A student graphs the movement of a motorized cart across the football field. Identify the dependent variable in this graph.
Alborosie

Answer:

Velocity.

Explanation:

The dependent variable is dependent on the independent variable. Basically, in order for the dependent variable to happen, the independent variable needs to do something first. Usually on a graph, <em>x</em> is the independent variable, and <em>y</em> is the dependent variable. In this situation, the time (x) needs to be graphed in order to track the velocity (y) on the graph.

The other answers are valid, but are not listed on the graph. Unless something is implied with a specific answer (like saying that speed and velocity are considered one on one side of the graph), the other answers wouldn't be correct.

I hope this helps.
