What happens to genetic information before a cell divides?
Before a cell divides, its genetic information is duplicated during the S phase of interphase. This ensures that each daughter cell receives a complete set of genetic material. The duplicated genetic material is then condensed into chromosomes for proper segregation during cell division.
Crossing over and the separation of duplicated homologous chromosomes in the first division produce genetic variation?
Crossing over during meiosis results in the exchange of genetic material between homologous chromosomes, creating new combinations of alleles. During the first division of meiosis, duplicated homologous chromosomes are separated, resulting in the formation of haploid cells with unique genetic content due to the random assortment of chromosomes.
Is an animal a eukaryote or a prokaryote?
An animal is a eukaryote. Eukaryotes have complex cell structures with a nucleus that houses their genetic material, while prokaryotes do not have a nucleus and their genetic material floats freely in the cell.
When is DNA duplicated and why is DNA duplicated?
DNA is duplicated during the S phase of the cell cycle, prior to cell division. DNA is duplicated to ensure that each new cell receives an exact copy of the genetic information, allowing for the accurate transmission of genetic material to the daughter cells.
Is a hydra a prokaryote or a eukaryote?
A hydra is a eukaryote. It is a multicellular organism that has membrane-bound organelles and a true nucleus containing its genetic material.
What happens to genetic information before a cell divides?

Where is genetic information stored and duplicated?
The genetic material of cells is stored in the nucleolus. It is duplicated by ribosomes in the nucleus.
In what process are chromosomes duplicated?
Chromosomes are duplicated during the S phase of the cell cycle in a process called DNA replication. This ensures that each daughter cell receives a complete set of genetic material during cell division.
Why do you think DNA is duplicated before a cell divides and what is the significance of this process in cell division?
DNA is duplicated before cell division to ensure that each new cell receives a complete set of genetic information. This process is crucial in cell division because it allows for accurate transmission of genetic material to offspring cells, ensuring genetic stability and proper functioning of the new cells.
Are joined strands of duplicated genetic material?
Chromosomes and sister chromatids are joined strands of duplicated genetic material. A chromatid is one copy of a duplicated chromosome which, before replication, is composed of one DNA molecule.
What structure identifies a eukaryote as a eukaryote?
There is no nuclear envelope that encloses the genetic material in prokaryotes.
Joined strands of duplicated genetic material are know as?
diploids
Which type of cell division is called the duplication division?
The type of cell division that is known as the duplication division is called DNA replication. During DNA replication, the genetic material is duplicated to maintain the genetic information in the daughter cells during cell division.
Is bamboo a eukaryote?
Yes, bamboo is a eukaryote. This means that its cells have a membrane-bound nucleus containing its genetic material.
The chromosomal DNA is duplicated in what?
The chromosomal DNA is duplicated during the S phase of the cell cycle. This process ensures that each daughter cell receives a complete set of genetic material during cell division.
