For DNA replication to proceed normally, several key enzymes are required, including DNA helicase, which unwinds the double-stranded DNA, and DNA polymerase, which synthesizes new DNA strands by adding nucleotides complementary to the template strand. Additionally, primase is necessary to synthesize RNA primers, providing a starting point for DNA polymerase. Finally, DNA ligase is essential for joining Okazaki fragments on the lagging strand, ensuring the newly synthesized DNA is continuous.

What is the role of the helipase enzyme in DNA replication?
Helicase is an essential enzyme in DNA replication responsible for unwinding the double-stranded DNA molecule. It separates the two strands by breaking the hydrogen bonds between the nucleotide bases, creating a replication fork. This unwinding allows other enzymes, such as DNA polymerase, to access the single-stranded DNA templates for synthesis of new complementary strands. Without helicase, DNA replication cannot proceed efficiently.
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 happens during g1 interphase?
cell grows and carries out its normal functions.
Explain what enzymes do that is essential for cell function?
Enzymes are biological catalysts that accelerate chemical reactions in cells, making them essential for various metabolic processes. They lower the activation energy required for reactions, allowing cellular functions to occur at a rate compatible with life. By facilitating processes such as digestion, energy production, and DNA replication, enzymes ensure that cells can efficiently carry out their necessary functions while maintaining homeostasis. Without enzymes, many vital reactions would proceed too slowly to sustain life.
What is the relationship of genes and enzymes?
The link is that a metabolism is made up of different reactions and these reactions have to be catalyzed by enzymes, because without these enzymes most of the reactions in the metabolism wouldn't proceed.
DNA replication occurs with or without the aid of enzymes?
DNA replication requires the aid of enzymes. Enzymes like DNA polymerase and helicase are crucial for unwinding the DNA double helix, synthesizing new DNA strands, and proofreading and repairing any errors that may occur during replication. Without these enzymes, DNA replication cannot proceed effectively and accurately.
Which process in eukaryotic cells will proceed normally whether oxygen is present or absent?
Glycolysis is a metabolic process in eukaryotic cells that can proceed normally in the absence of oxygen. It converts glucose into pyruvate, producing ATP as an energy source for the cell.
How do enzyms function?
Enzymes allow reactions to occur at body temperature, that would not normally occur at that temperature. They accomplish this by lowering the amount of activation energy needed to have the reaction proceed.

Which process in eukaryotic cells will proceed normally whether oxygen (O2) is present or absen?
Glycolysis is a process in eukaryotic cells that will proceed normally whether oxygen is present or absent. Glycolysis breaks down glucose to produce ATP, the cell's energy currency, and occurs in the cytoplasm. It does not require oxygen and is the first step in both aerobic and anaerobic respiration pathways.
Proceed in present tense?
The present tense is proceeding.

cell grows and carries out its normal functions.

How would reactions be affected if enzymes were not present in cell?
enzymes are the catalyst that aid the reactions taking place inside our bodies. if there were no enzymes, our metabolic processes would slow down to such a rate that we would not be able to survive.
What does an enzyme do to activation energy?
Enzymes reduce the activation energy required for a chemical reaction to occur by stabilizing the transition state of the reaction. This allows the reaction to proceed more rapidly than if it were to occur without the enzyme present.
