What happens to the chromosome before an animal cell divides?
The chromosomes have to split and go to opposite sides of the cell.
During binary fission of prokaryotes both the original and the duplicated chromosomes attach to what before the cell divides in half?
The original and duplicated chromosomes attach to the cell membrane or the plasma membrane before the cell divides in half during binary fission in prokaryotes. This ensures that each daughter cell receives a complete set of chromosomes.
When a body cell divides through the process of mitosis what is the number of chromosomes in the daughter cells?
After mitosis each daughter cell contains 46 chromosomes as the DNA replicates itself before the cell divides
How many chromosomes are in a human cell before and after meiosis?
When meiosis begins at Gap 1 phase (G1) the cell of a human has 46 chromosomes or 2n.
What condenses into an X shape before mitosis?
Chromosomes condense into an X shape before mitosis. During prophase, the chromatin in the nucleus begins to condense and coil, forming distinct X-shaped structures known as chromosomes. This condensation allows the chromosomes to be easily moved and segregated during cell division.
What do chromosomes look like before and after the S phase of the cell cycle?
Before the S phase of the cell cycle, chromosomes appear as single strands of DNA. After the S phase, they replicate and become double-stranded, forming sister chromatids.

Why does a cell make a copy of itself before it divides?
So that the new cells have the same chromosomes as the parent 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.
Why are DNA strands wound into the tight gene packages of chromosomes before mitosis begins?

How do chromosomes duplicate before dividing in meiosis?
During meiosis, chromosomes duplicate through a process called DNA replication. This involves the separation of the two strands of the DNA molecule and the synthesis of new complementary strands. This results in two identical copies of each chromosome, known as sister chromatids, which are then separated during cell division.
What condenses into an X shape before mitosis?
Chromosomes condense into an X shape before mitosis. During prophase, the chromatin in the nucleus begins to condense and coil, forming distinct X-shaped structures known as chromosomes. This condensation allows the chromosomes to be easily moved and segregated during cell division.
What are 2 identical strands of 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 is the name for when chromosomes look like mixed up threads?
The word chromatin matches what you are looking for. The DNA looks like this before it condenses before the cell divides. It is open so that the genes can be active.
