During mitosis and meiosis, DNA is replicated by a process called DNA replication. This process involves the unwinding of the DNA double helix, the separation of the two strands, and the synthesis of new complementary strands using the existing strands as templates. This results in two identical copies of the original DNA molecule. In mitosis, DNA replication occurs once, resulting in two identical daughter cells. In meiosis, DNA replication occurs twice, resulting in four daughter cells with half the number of chromosomes as the original cell.
What else can I help you with?
Is DNA replicated during mitosis or meiosis?
DNA is replicated during the S phase of the cell cycle before both mitosis and meiosis.
Is DNA replication involved in mitosis or meiosis?
DNA replication is involved in both mitosis and meiosis.
Does DNA replication occur after telophase 1?
Telophase is a phase of mitosis. DNA replication must occur before mitosis begins. If it does not then the DNA chromosomes may not be consistent throughout the division of the cells.
What 2 cell division processes use DNA replication?
Mitosis and meiosis are the two cell division processes that utilize DNA replication. During both processes, DNA is replicated in the S phase of the cell cycle to ensure that each daughter cell receives an identical copy of the genetic material.
Before mitosis or meiosis DNA coils into what?
Before mitosis and meiosis, DNA is loose in the form of chromatin, then it coils into chromosomes right before the mitosis and meiosis.
Is DNA replicated during mitosis or meiosis?
DNA is replicated during the S phase of the cell cycle before both mitosis and meiosis.
What is a characteristic of meiosis and not meiosis?
The daughter cells produced are genetcally identical. A mitosis divides cells, which still contains the same number on chromosomes. In mitosis DNA is replicated once, and the nucleus divides once. In meiosis DNA is replicated once, but the nucleus is divided twice.
When does replication happen during mitosis or meiosis?
Replication occurs during the S phase of the cell cycle before both mitosis and meiosis. In mitosis, the replicated DNA is separated into two identical daughter cells. In meiosis, the replicated DNA is separated into four haploid daughter cells with genetic variation.
What is a characteristic of mitosis and not of meiosis?
The daughter cells produced are genetcally identical. A mitosis divides cells, which still contains the same number on chromosomes. In mitosis DNA is replicated once, and the nucleus divides once. In meiosis DNA is replicated once, but the nucleus is divided twice.
Does chromosome replication occur in mitosis and meiosis?
Chromosome replication occurs before both mitosis and meiosis. During the S phase of the cell cycle, DNA is replicated in preparation for cell division. In mitosis, replicated chromosomes are separated into two identical daughter cells, while in meiosis, replicated chromosomes are separated twice to produce haploid gametes.
Is DNA replication involved in mitosis or meiosis?
DNA replication is involved in both mitosis and meiosis.
Does DNA replication occur after telophase 1?
Telophase is a phase of mitosis. DNA replication must occur before mitosis begins. If it does not then the DNA chromosomes may not be consistent throughout the division of the cells.
What is the DNA of mitosis?
There is no DNA of mitosis. Before mitosis, the DNA must be replicated, which occurs during interphase of the cell cycle.
What 2 cell division processes use DNA replication?
Mitosis and meiosis are the two cell division processes that utilize DNA replication. During both processes, DNA is replicated in the S phase of the cell cycle to ensure that each daughter cell receives an identical copy of the genetic material.
Before mitosis or meiosis DNA coils into what?
Before mitosis and meiosis, DNA is loose in the form of chromatin, then it coils into chromosomes right before the mitosis and meiosis.
DNA is replicated just prior to this step?
meiosis 1
What is the process of cell division involve in sexual reproduction that produces gametes?
It is called meiosis. It works very similarly to mitosis, but the DNA isn't replicated once it has divided.
