The double helix structure of DNA is so famous it serves as a sort ... each other like normal (adenine to thymine on the opposite strand, cytosine to guanine) cytosines on the same strand hook ...

When a cell divides, it makes a copy of its DNA instructions for the new cell. The twisted double strand structure -- the famed double helix -- unwinds and the strands separate. The nucleotides (A ...

DNA (deoxyribonucleic acid), the molecular "blueprint" carrying the genetic instructions that influence the growth, ...

In both cases, replication occurs so quickly because multiple polymerases can synthesize two new strands at the same time by using each unwound strand from the original DNA double helix as a template.

These predictions were as follows: According to the semiconservative model, after one round of replication, every new DNA double helix would be a hybrid that consisted of one strand of old DNA ...

Researchers at the Chambers University of Technology have discovered that water is why DNA strands are wrapped around each other and have a helix shape. Understanding how DNA repairs itself could ...

DNA replication is the process by which the DNA molecule makes an exact copy of itself during cell division. The double helix unwinds, and each strand serves as a template for the synthesis of a new ...

Not all DNA is in the double helix form described in textbooks since the 1950’s. Quadruple helix DNA, also known as G-quadruplex DNA, was identified in the human genome several decades ago, and ...

This unwinding of the helix is caused by an enzyme (helicase ... RNA polymerase moves along the DNA strand. Free RNA nucleotides form hydrogen bonds with the exposed DNA strand nucleotides by ...
