First helicase separates the two strands of DNA and then DNA polymerase adds nucleotides following the base pair rule.
It is important because scientific theories are not proven, hence the reason they are called theories. Adding information overtime to these theories can help validate the reliability of said theories.
Answer:
The carbon cycle is nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.
Explanation:
The similarity just lies in the structure. DNA is double-stranded, however it is twisted/helical, while the ladder does not twist. However, other than that, they are quite similar. The 2 strands (5' -> 3' and 3' -> 5') of DNA serve as the 2 vertical sides of the ladder. The base pairs of DNA are what connect the two strands together. So, in terms of the ladder, think of the steps of the ladder as the base pairs. Think each step as consisting of 2 entities joining together to make 1 big step. For example, think of a step having 2 halves down the middle. 1 half would be a guanine (base) and the other half would be a cytosine (base). Guanine is connected to the 5' --> 3' strand (Left vertical side of ladder) while the Cytosine is connected to the 3' --> 5' strand (right vertical side of ladder). These two come together at one of their ends and base pair, which appears to look like the steps on a ladder.
