DNA replicates during what phase?

It replicates during Interphase, the stage of Mitosis.DNA is replicated during interphase. This DNA replication takes place during mitosis and allows the daughter cells to have the correct number of chromosomes.


Why are all chromosomes condense during all stages of the cell cycle?

When replicating or during transcription, DNA needs to uncoil in order to give the proper code. When the chromosomes are condensed, it cannot uncoil itself to give any sort of message. In order for the cell to remain functional, it must be able to code DNA.


Why is it important for DNA to uncoil during DNA replication?

Since DNA is highly coiled to pack a huge amount of heredity information into a small space, it has to be unwound before transcription can begin. If it were still coiled, the proteins involved in the process of transcription cannot gain access to the internal regions DNA

What is the function of ethidium bromide in DNA extraction?

Ethidium bromide is a fluorescent dye that binds to DNA, allowing for visualization of the DNA under ultraviolet light during gel electrophoresis. It helps researchers to track the movement of DNA fragments in the gel and determine their sizes accurately during the DNA extraction process.

Why are the chromosomes not condensed during all stages of mitosis?

When replicating or during transcription, DNA needs to uncoil in order to give the proper code. When the chromosomes are condensed, it cannot uncoil itself to give any sort of message. In order for the cell to remain functional, it must be able to code DNA.
