What separates the DNA strands during replication?

During replication, the DNA strands are separated by an enzyme called helicase. Helicase unwinds the double helix structure of DNA, breaking the hydrogen bonds between the base pairs and allowing the strands to separate for replication to occur.


The junction between a motor neurons axon and the muscle cell membrane is called a neuromuscular junction or a?

The junction between a motor neruon's axon and the muscle cell membrane is called a neuromuscular junction or a myoneuraljunction?


What are DNA strands held together by hydrogen bonds separated by?

Hydrogen bonding infers that the two strands are VERY close together so the strands are practically right next to each other. As the strands wind up in a larger scale they wrap around proteins to keep them secure and finally form a combined material called chromatin which make up chromosomes in eukaryote cells.


DNA strands held together by hrydrogen bonds are separated by an?

I wanna say deoxyribose but I'm not completely sure


What causes two strands of DNA to split?

The answer depends on the circumstances! In a cell, during DNA replication or during translation, the two strands in a DNA molecule are separated by enzymes called topoisomerases and helicases. In a solution, the two strands of a DNA molecule can be separated by being heated. This is called DNA melting. See: http://en.wikipedia.org/wiki/DNA http://en.wikipedia.org/wiki/DNA_melting


The point of contact between the nerve and the muscle fibers it stimulates is called a?

The point of contact between the nerve and the muscle fibers it stimulates is called a neuromuscular junction. This junction allows for communication between the nervous system and the muscular system, facilitating muscle contraction in response to nerve impulses.


What is the junction between atria and ventricles called?

Annulus fibrosus cordis


The first step of DNA replication is to copy part of the DNA sequence into?

The first step of DNA replication is to unwind and separate the two strands of the double helix. This process is initiated by enzymes called helicases. Once the strands are separated, they serve as templates for the synthesis of new complementary strands.


A junction that is a protein channel linking the cytoplasms of adjacent cells is called?

A junction that is a protein channel linking the cytoplasms of adjacent cells is called a gap junction. This structure allows for direct communication and sharing of ions and small molecules between neighboring cells.


What is the junction called between 2 communicating neurons?

The junction between two communicating neurons is called a synapse. At the synapse, electrical signals called action potentials are converted into chemical signals in the form of neurotransmitters, which then travel across the synaptic cleft to relay the signal to the next neuron.


Why is Scotch Corner on the A1 called the Scotch Corner?

The name originates from being the junction where travelers to eastern Scotland are separated from travelers to western Scotland.


What is the point of contact between a motor neuron and a skeletal muscle cell called?

This point is often called the neuromuscular junction or motor end plate. ?The neurotransmitter used here is acetylcholine.Many diseases occur with dysfunction at this junction, like Myesthenia Gravis, botulism, or Lambert Eaton Myasthenic Syndrome.
