Before replication can begin, the parent cell must undergo a period of growth and DNA must be duplicated during the S phase of the cell cycle. Additionally, the cell must ensure that all necessary molecules and enzymes required for replication are available.

Explain why DNA replication must occur before mitosis starts?
DNA replication must occur before mitosis starts to ensure that each daughter cell receives a complete and identical copy of the genetic information. If DNA replication did not occur before mitosis, the daughter cells would have only half of the necessary genetic material, leading to genetic abnormalities and potentially cell death.
Which which job must enzymes do before replication can begin?
Unwind part of the original DNA molecule :)
What must occur before DNA replication can take place?
Before DNA replication can take place, the DNA molecule must unwind and separate into two strands, a process catalyzed by enzymes. This separation into single strands allows for the complementary base pairing to occur during replication. Additionally, a primer made of RNA is needed to initiate the process by providing a starting point for DNA polymerase to add nucleotides.
Which job must enzymes do before replication can begin?
They must unwind part of the original DNA molecule.
What k must happen before meiosis can begin?
A duplication of the chromosomes is what must happen before meiosis can begin.
What must occur before replication can?
the double helix must unwind
In what part of the cell does the replication occur?
DNA replication occurs during Interphase. This is not normally part of the cell division cycle but interphase must occur before subsequent stages such as prophase and metaphase can occur.
Explain why DNA replication must occur before mitosis starts?
DNA replication must occur before mitosis starts to ensure that each daughter cell receives a complete and identical copy of the genetic information. If DNA replication did not occur before mitosis, the daughter cells would have only half of the necessary genetic material, leading to genetic abnormalities and potentially cell death.
What event must occur outside the nucleus before mitosis can begin?
Before mitosis can happen, the chromosomes inside the nucleus must separate to form identical pairs. This sets the stage for each of the daughter cells to have a copy of the DNA to replicate the full sequence.
Why DNA have to replicated before cell division?
DNA replication must occur before cell division to make sure that the daughter cells are genetically identical.

Does DNA replication occur after telophase 1?
No, DNA replication occurs before meiosis, during the S-phase of interphase. Once meiosis begins, the DNA is already replicated, and the duplicated chromosomes are separated during meiosis I and II.
Which process must occur before any cell division can take place?
DNA replication must occur before cell division can take place. This process ensures that each new cell receives an identical copy of the genetic material to maintain genetic continuity.
