What is done to the DNA to make the bands visible in gel electrophoresis?
In gel electrophoresis, DNA is treated with a dye that binds to the DNA molecules, making them visible as bands under ultraviolet light.
What makes DNA visible?
You can an electrophoresis gel and then stain the gel using a solution such as coomassie blue to make the bands visible. Alternatively, you can stain a cell containing DNA by using acridine orange. It is necessary to observe these under an electron light microscope.
Why is PCR a necessary step in the analysis of a DNA sample?
PCR, or polymerase chain reaction, is necessary in DNA analysis because it allows for the amplification of a small amount of DNA into a larger, more easily detectable quantity. This process is crucial for various applications, such as forensic analysis, genetic testing, and research, where only a limited amount of DNA is available for analysis.
Which pair of enzymes is necessary to make recombinant DNA?
Restriction enzymes and DNA ligase are necessary to make recombinant DNA. Restriction enzymes are used to cut the DNA at specific sequences, while DNA ligase is used to join together pieces of DNA from different sources.
DNA is used as a blueprint to make this molecule?
In the process of transcription, DNA is used as a blueprint to make m-RNA which codes for a specific protein.

The final step in the hybridization of radioactively DNA and normal DNA is to?
Make a solution with the two types of DNA
What step is not essential in producing recombinant DNA?
One non-essential step in producing recombinant DNA is incorporating a selection marker gene. While this can be useful for identifying cells that have successfully taken up the recombinant DNA, it is not absolutely necessary for the process of creating recombinant DNA itself.
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.
How can you tell if isolated RNA is free of DNA?
There is a DNA killing step in RNA isolation by the enzyme DNase I. This will make sure your preparation is free of DNA.
What is the function of 2-propanol in DNA extraction?
2-propanol is used in DNA extraction to precipitate DNA from the mixture. When added to the sample, it causes the DNA molecules to come out of solution and form a visible clump that can be easily separated. This step allows for the separation and purification of DNA from other components in the sample.
Why grind the liver in a DNA extraction lab?
Grinding the liver helps break down the cell membranes and release the cellular contents, including the DNA. This step is necessary to access the DNA trapped inside the liver cells and to make it available for further extraction and analysis.

When is a copy of DNA necessary?
ANSWER: A copy of DNA is necessary in the process of protien synthesis.
What do male sperm cells do?
They provide 50% of the DNA material necessary to make a baby !
What is a DNA repair enzyme activated by visible light?
DNA photolyase
