What else can I help you with?
What enzyme breaks the bonds between the complementary parent strands?
The enzyme that breaks the bonds between the complementary parent strands during DNA replication is DNA helicase. DNA helicase unwinds the double helix by breaking the hydrogen bonds between the base pairs, allowing for the strands to separate and be copied.
What enzyme adds base pairs in order to create the new strands in DNA replication?
DNA polymerase is the enzyme responsible for adding complementary nucleotides to the template strand during DNA replication. It creates the new strands by catalyzing the formation of phosphodiester bonds between the nucleotides.
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.
When a DNA molecule unzips?
bases within the cells nucleus pair with the separated bases on the DNA strand
What does helicase do in replication?
(Apex) It breaks apart the bases.
In order to replicate where do DNA molecules separate?
DNA molecules separate or unwind at specific sites known as replication origins. These regions serve as starting points for the enzyme complex that unwinds the DNA strands, creating a replication fork. DNA replication occurs bidirectionally from each origin, with the two strands being replicated simultaneously.
What enzyme builds mRNA molecules bases on the code in DNA?
The enzyme is RNA polymerase.
What occures when 2 strands unzip and the nitrogen bases pair with different nitrogen bases?
This is the process of DNA replication. A DNA strand in the nucleus of a cell, starts off by being "unzipped" by helicase (an enzyme). Then another enzyme, DNA polymerase matches the nitrogen bases (which are freely floating in the nucleus), of each half with their matches, this forms two identical strands, of DNA.
When DNA is about to be copied where does it split?
It splits down the middle due to the action of the enzyme helicase. This exposes the nitrogen bases on both strands of the DNA.
The two strands of DNA molecules are held together by?
hydrogen bonds between complementary nitrogenous bases.
The enzyme that is responsible for replicating molecules of DNA by attaching complementary bases in the correct sequence is?
DNA polymerase
What enzyme breaks the bonds between the complementary parent strands?
The enzyme that breaks the bonds between the complementary parent strands during DNA replication is DNA helicase. DNA helicase unwinds the double helix by breaking the hydrogen bonds between the base pairs, allowing for the strands to separate and be copied.
What chemicals connect to what in a dna strand?
The backbone of the DNA molecule is composed of alternating deoxyribose sugars and phosphate groups. The nitrogen bases are bonded to the sugar molecules. The two strands of DNA are held together by hydrogen bonds between the nitrogen bases of both strands.
How do you describe the basic structure of the DNA molecules?
DNA is composed of two strands of DNA nucleotides, arranged into a double helix, often referred to as a twisted ladder. The sides of the ladder are composed of alternating deoxyribose sugar molecules and phosphate molecules, and the rungs of the ladder are the pairs of nitrogen bases. The two strands of DNA nucleotides are held together by hydrogen bonds which form between the paired nitrogen bases.
What factor maintains the same distance between strands in DNA molecules?
Depending on what "Strands" are it could be either Hydrogen bonding between complementary base pairs or Phosphate bonds between interlinking deoxyribose sugars
How many bases does a double helix have after the complementary strand is added?
A double helix has twice the number of bases in one strand, so after adding the complementary strand, the double helix will have the sum of the bases in both strands. This is because each base pairs with its complementary base (A with T, and G with C) across the two strands.
Which enzyme is added to attach the DNA backbone between vetor and foreign DNA that have formed bases pairs at sticky ends during of recombinant DNA?
DNA ligase is added.
