DNA in cell lysate can be made visible through various techniques such as agarose gel electrophoresis or polymerase chain reaction (PCR). In agarose gel electrophoresis, DNA is separated based on size and can be visualized using a DNA stain under UV light. In PCR, specific DNA fragments are amplified and visualized using gel electrophoresis.

When do chromosomes become visible in the nucleus of a cell?
Chromosomes become visible in the nucleus of a cell during cell division, specifically during the prophase stage of mitosis or meiosis when the DNA condenses and coils tightly. This allows the chromosomes to be distinguished under a microscope.
In what phase does the nucleus and nucleolus become visible?
I am pretty sure it's Prophase. But you should look it up just to make sure.No, that answer is wrong. It's Telophase. The nucleolus does the opposite and begins to disappear during Prophase.
What happens to the DNA in prophase of the cell cycle?
During prophase of the cell cycle, the DNA condenses and coils tightly to form visible chromosomes. This process helps to organize and prepare the DNA for cell division.
What is the function of salt in DNA extraction?
Salt helps to neutralize the charges on the DNA phosphate backbone and the proteins present in the cell lysate, allowing DNA molecules to clump together and precipitate out of solution. This step helps to separate DNA from other cellular components during the extraction process.
Chromosomes first become visible during?
Chromosomes first become visible during cell division, specifically during mitosis and meiosis. As the cell prepares to divide, the DNA condenses and coils tightly to form chromosomes, which can be seen under a microscope. This helps to ensure accurate distribution of genetic material to daughter cells.
How does DNA in the cell lysis solution become visible?
hi
When does DNA and nuclear proteins become visible in the cell cycle?
prophase
When cell chromosome become visible what are the duplicate strands of DNA called?
Daughter Chromosomes
What are only visible when a cell is preparing to divide?
Chromosomes, which consist of DNA and proteins, are only visible when a cell is preparing to divide. These structures condense and become visible under a microscope during cell division, allowing for the precise distribution of genetic material to daughter cells.
What happens for Dna to become more visible in the Cell?
During cell division, the DNA condenses into tightly coiled structures called chromosomes, which become more visible under a microscope. This condensation helps ensure that each daughter cell receives a full set of genetic material during cell division. Additionally, histone proteins play a role in packaging and organizing DNA, further contributing to its visibility within the cell.
When does DNA become visible?
DNA is never visible to a naked eye but you can see chromosomes filled with DNA in mitosis during prophase.
When do chromosomes become visible in the nucleus of a cell?
Chromosomes become visible in the nucleus of a cell during cell division, specifically during the prophase stage of mitosis or meiosis when the DNA condenses and coils tightly. This allows the chromosomes to be distinguished under a microscope.
When is the genetic material visible in a cell?
DNA is visible during mitosis (replication) when the chromosomes condense.
What is role of CTAB - NaCl?
Often used to purified crude cell lysate by precipitating proteins, lipids and polysaccarides out of solution. This leaves only nucleic acid (DNA, RNA) in the supernatant.
Are chromosomes always visible in a eukaryote cell?
In a normal eukaryotic cell which is not actively dividing, chromosomes are not visible. The DNA is loosely coiled, dispersed through the nucleoplasm. However, during cell division, the DNA condenses into ordered structures called chromosomes, which are visible under the microscope.
What are chromosomeswhere and when they are visible in the cell?
Chromosomes contain tightly-packed DNA, and are visible only when the cell is preparing to replicate (before mitosis/meiosis).
In what phase does the nucleus and nucleolus become visible?
I am pretty sure it's Prophase. But you should look it up just to make sure.No, that answer is wrong. It's Telophase. The nucleolus does the opposite and begins to disappear during Prophase.
