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?
Helicase enzymes are responsible for unwinding and separating the two strands of nucleotides in DNA during processes like replication and transcription. These enzymes use energy from ATP hydrolysis to break the hydrogen bonds between the base pairs, allowing the strands to separate.
How enzymes work by?
lowering the energy needed to break bonds.

Why are enzymes called makers and breakers?
Enzymes are called makers because they facilitate chemical reactions that build or create molecules in the body. They are called breakers because they also catalyze reactions that break down larger molecules into smaller components for energy production or elimination. Thus, enzymes play a crucial role in both building and breaking down substances in the body.
What Unwinds the DNA strand and breaks the hydrogen bonds between nucleotides in preparation for replication?
Enzymes called helicases are responsible for unwinding the DNA double helix, separating the two strands. Another enzyme called topoisomerase helps relieve tension that builds up ahead of the replication fork. These processes break the hydrogen bonds between nucleotides, allowing the DNA strands to separate and serve as templates for replication.
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.
How enzymes work by?
lowering the energy needed to break bonds.
Do enzymes break bonds?
Yup sugar, i believe so
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
