What bonds do helicase and polymerase enzymes break?
Helicase enzyme breaks hydrogen bonds between base pairs in DNA strands to unwind the double helix structure. Polymerase enzyme breaks the bonds between nucleotides in the DNA strand being replicated, allowing for the addition of new nucleotides during DNA replication.
The weak chemical bonds importat in holding the DNA double helix together is the?
The two strands of DNA nucleotides are held together by hydrogen bonds between complimentary nitrogen bases. Adenine pairs with guanine and cytosine pairs with thymine. When it is time for a cell to reproduce, and during protein synthesis, an enzyme called helicase breaks the hydrogen bonds between the two strands. This way DNA can be replicated in preparation for cell reproduction or it can be used as a template for protein synthesis.
What specifically breaks the rungs of the DNA ladder?
The enzyme helicase separates the nitrogen base pairs, or rungs, of the DNA ladder.
What is the role of decomposes in the nitrogen cycle?
Decomposers have a very important role in the nitrogen cycle. They convert nitrogen found in other organisms into ammonia so it can be returned to the soil. Some use a process called denitrification to return nitrogen directly to the atmosphere.
What is the chemical change called when something combined breaks apart?
In chemistry it is called decomposition. This is when a compound with multiple elements gets broken down into pure elements like hydrogen and nitrogen... That is how we get nutrition from the food we eat (it is what happens in the stomach).
What do DNA polymerase do in DNA replication?
It breaks the hydrogen bonds between the base pairs
What mechanism breaks the hydrogen bonds in DNA replication?
During DNA replication, the enzyme helicase breaks the hydrogen bonds between the two strands of DNA, allowing the strands to separate and be copied.
What mechanism breaks hydrogen bonds in DNA?
The enzyme helicase breaks hydrogen bonds in DNA.
What enzyme breaks hydrogen bonds between nitrogen bases?
Helicase and RNA polymerase separate DNA strands by breaking the hydrogen bonds between complementary bases.Helicase parts the strands of DNA during DNA replication, and RNA polymerase parts them during transcription.The enzyme that separates DNA in called DNA helicases. There are two of them that work away from the origin of replication, creating in "bubble" in the DNA molecule. For eukaryotes, there would be several origins of replication but in prokaryotes, there is only one origin of replication.
A hydrogen bond can form between a hydrogen atom of one molecule and which atom of another molecule?
since hydrogen atom has no electron in its shell, it acquires positive charge. when a negatively charged atom comes in contact with hydrogen atom, it donates h atom a electron to make a covalent bond. but when it breaks the negative atom restores its electron.
What does helicase do in replication?
(Apex) It breaks apart the bases.
What is hydrogen peroxidase?
It is an enzyme that breaks down Hydrogen Peroxide.
What happens when hydrogen iodide breaks down?
When hydrogen iodide breaks down, it forms hydrogen gas and iodine vapor. The reaction is reversible, meaning that hydrogen iodide can reform if hydrogen gas and iodine are combined.
What breaks the bonds between the nitrogen bases of the DNA molecule?
Your answer is "Helicase". This is the enzyme responsible for the unzipping of the DNA molecule, or in other words, the breakage of the bonds of its nitrogen bases.
When water is heated most of the energy that water initially absorbs is used to?
It breaks the hydrogen bonds between the water molecules
Why do abnormal elevated temperatures degrade proteins?
The heat breaks the hydrogen bonds between the amino acids, and the shape is changed.
Which enzyme breaks the hydrogen bonds during DNA replication?
The enzyme that breaks the hydrogen bonds during DNA replication is called helicase.
