What else can I help you with?
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.
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 enzyme unzips the DNA molecule?
There are several enzymes that 'unzip' DNA. These enzymes are collectively known as DNA helicases. DNA helicases are helix-destabilizing enzymes that bind to DNA at the origin of replication and break hydrogen bonds, thereby separating the two strands. This allows RNA polymerase to begin transcription (copying) of the DNA sequence.
What enzymes help separate the two strands of nucleotides in DNA?
DNA Polymerase is the enzyme that seperates the two strands so that messenger RNA can read the genetic information of the DNA. The mRNA then moves two tranfer RNA so that Protien synthesis may occur.
How enzymes work by?
lowering the energy needed to break bonds.

Why are enzymes called makers and breakers?
In genetics, an enzyme known as DNA polymerase effects the copying of DNA there for it helps in replication, as in MAKING, another enzyme known as DNA helicase is used to break the bonds on the nitrogen bases so the strands can separate, BREAKING bonds.
What Unwinds the DNA strand and breaks the hydrogen bonds between nucleotides in preparation for replication?
The initiation complex makes a small gap for a helicase enzyme to bind. It is the helicase the 'undwinds' the DNA for most of replication. In E. coli, for example, DnaA protein binds DNA to make a small gap between the two DNA strands, where DnaB enzyme (a helicase) can bind to the lagging strand (the one that is copied in fragments). From there, DnaB unwinds the DNA ahead of the polymerase enzyme.
Does helicase break hydrogen bonds?
Yes, helicase breaks hydrogen bonds between the nitrogenous base pairs of DNA during replication, allowing the double helix to unwind and separate into two single strands. This process is essential for the replication of DNA.
Do enzymes break bonds?
Yup sugar, i believe so
How enzymes work by?
lowering the energy needed to break bonds.
What unzips DNA so it can duplicate?
Enzymes called helicases are responsible for unzipping the DNA double helix so that it can be duplicated. Helicases break the hydrogen bonds between the paired nucleotides of the DNA strands, allowing the strands to separate and serve as templates for the synthesis of new DNA strands during replication.
What creates enzymes that break down carbohydrates and proteins?
Peptide bonds
Do Enzymes raise the activation energy to break the bonds of reactant molecules?
Yes
