When during the cell cycle does DNA condense into chromosomes?
DNA condenses into chromosomes during the prophase stage of the cell cycle.
At what phase of the cell cycle does DNA condense into chromosomes?
DNA condenses into chromosomes during the prophase stage of the cell cycle.
How does DNA replicate during prophase in the cell cycle?
During prophase in the cell cycle, DNA replicates by unwinding and separating into two strands. Enzymes called DNA polymerases then create new complementary strands by adding nucleotides to each original strand. This process results in two identical copies of the DNA molecule.
What stage of the cell cycle is a cell's DNA copied?
The stage in the cell cycle where DNA is replicated is actually in interphase, before the nuclear membrane dissolves in prophase. * The DNA is replicated at mid-interphase (in the S phase), between the two growth phases (G1 and G2). So replication precedes division by several hours in a typical cell.
What happens from interphase to prophase?
the DNA has condensed from chromatin into chromosomes Interphase has three distinct phases: G1, S, and G2. In G1, the cell grows after its last mitosis cycle. In S (for "synthesis"), the cell synthesizes another copy of DNA. In G2, the cell doubles all the organelles and prepares for the beginning of mitosis. During prophase, chromatin condenses into chromosomes and the nuclear envelope breaks down.
What is the stage in the cell cycle when the DNA is copied?
Prophase
When during the cell cycle does DNA condense into chromosomes?
DNA condenses into chromosomes during the prophase stage of the cell cycle.
At what phase of the cell cycle does DNA condense into chromosomes?

When does DNA and nuclear proteins become visible in the cell cycle?
prophase
How does DNA replicate during prophase in the cell cycle?

When does the process shown occur in the cell cycle?
The specific process that occurs in the cell cycle can vary depending on the stage. In general, DNA replication occurs during the S phase, chromosome segregation happens during the mitotic phase, and cell division occurs during cytokinesis.
If a skin cell has 40 micrograms of DNA during G1 how much DNA will it have during prophase?
During prophase, when the cell is preparing for cell division, the amount of DNA in a skin cell remains the same as in G1 phase. So, the skin cell will still have 40 micrograms of DNA during prophase.

What happens to a cells DNA in interphase prophase and metaphase?
In interphase, the cell's DNA replicates to form identical copies of each chromosome. In prophase, the DNA condenses into visible chromosomes and the nuclear envelope breaks down. In metaphase, the chromosomes line up along the cell's equator.
When the M phase begins during the cell cycle it starts with?
When the M phase, or mitosis, begins during the cell cycle, it starts with prophase. Prophase is the first stage of mitosis where chromatin condenses into visible chromosomes, the nuclear membrane breaks down, and the mitotic spindle begins to form.
How often does DNA replication occur in a cell's life cycle?
DNA replication occurs during the S phase of the cell cycle, which happens before cell division. This process typically occurs once in each cell cycle.
