What else can I help you with?
What are enzymes that open up the double helix by breaking the hydrogen bonds that like complementary bases?
Helicases are enzymes that unwind the DNA double helix by breaking the hydrogen bonds between complementary base pairs. These enzymes play a crucial role in processes like DNA replication, transcription, and repair by separating the two strands of DNA.
Nitrogen bases are split apart by what?
They are split apart by the enzymes helicase.
Which enzyme opens DNA molecules?
Restriction Enzymes
What enzymes help separarte the 2 strands of nucleotides on DNA?
DNA helicase
What happens when a helicase doesn't work?
Replication would be hard pressed to take place. Helicase is the enzyme that splits the double helix and unwinds this helix so that DNA polymerase can do it's job of running the leading and lagging strands of DNA in the replication process.
What enhances separation of DNA strands during replication?
Helicase enzymes are responsible for unwinding and separating the DNA strands during replication by breaking the hydrogen bonds between the bases. This creates the replication fork where new nucleotides can be added by DNA polymerase enzymes. ATP provides the energy needed for helicase to perform its unwinding function.
DNA polymerase and helicase are alike how?
Both DNA polymerase and helicase are enzymes involved in DNA replication. While DNA polymerase adds nucleotides to the growing DNA strand during replication, helicase unwinds the double-stranded DNA to facilitate replication. Both enzymes are essential for the accurate and efficient duplication of the genetic material.
What are the Examples of intra cellular enzymes?
RNA/DNA polymerases - Reverse Transcriptase. Helicase. Binding proteins. Enzymes simply act on a substrate - there are tonnes.
Does helicase enzymes break the sugar phosphate backbone?
No, helicase enzymes unwind and separate the double-stranded DNA helix by breaking the hydrogen bonds between complementary nucleotide base pairs. They do not break the sugar-phosphate backbone of the DNA molecule.
What molecule is first active during DNA replication?
helicase enzymes
What are the three enzymes involved in DNA transcription?
The three enzymes involved in DNA transcription are RNA polymerase, helicase, and topoisomerase. RNA polymerase is responsible for synthesizing RNA from a DNA template, helicase unwinds the DNA double helix, and topoisomerase helps to relieve the tension that builds up ahead of the replication fork.
What enzymes unwinding DNA double helix by breaking the hydrogen bonds to separate the complementary strands?
Helicase
