The protein uncoils the helix and "unzip" the bases
If you are talking about between the bases of DNA, then it is a Hydrogen bond. A hydrogen bond will break easily for replication when the helicase separates the DNA.
The process you're referring to is DNA replication. During DNA replication, the two sides of the double helix molecule unwind, creating two separate strands. Enzymes then attract new nucleotide bases to each strand, forming two new and identical DNA molecules.
They are there to allow for the expansion of the rails during hot weather.
Enzymes split the DNA molecule into two rails and then transport corresponding nitrogen bases to each rail.
Enzymes are essential for DNA replication because they facilitate the unwinding of the DNA double helix, the synthesis of new complementary strands, and the proofreading and repair of any errors that occur during replication. They also help regulate the process to ensure accurate and efficient copying of the genetic material.
The gap is there to prevent the rails expanding and buckling during very hot weather.
they have to work to help there parents
Men looking for work. They were called Hobos.
The inside rails inside of the main rails are called guard rails. They are there so that if there is a derailment the train will stay within the rails instead of off of the trestle.
You would need rails, detector rails, power rails, and minecarts.

riding the rails was a common term in the great depression. You hop on a train and ride the rails.
