Is DNA effective in identifying persons?

Yes, DNA is effective in identifying persons.


Can a toothbrush be used for DNA testing?

Yes, a toothbrush can be used for DNA testing. DNA can be collected from the bristles of the toothbrush used by an individual and sent to a lab for analysis. This can be useful in situations where other sources of DNA are not available.


Why is idoxuridine effective if host cells also contain DNA?

Idoxuridine is effective because it specifically targets viral DNA replication. While host cells contain DNA, idoxuridine is a nucleoside analogue that gets incorporated preferentially into viral DNA due to the higher replication rate of viruses. This incorporation disrupts viral DNA synthesis, leading to the inhibition of viral replication while causing minimal harm to host cell DNA, as host cells typically have slower replication rates and repair mechanisms that mitigate the drug's effects.


Beause many minerals are similar in color and certain elements may change color color is not a Identifier?

Color is not a good identifier of minerals.


Why does 10 degree Celsius ethyl alcohol work best for DNA extraction?

10 degrees Celsius ethyl alcohol is effective for DNA extraction because it helps to precipitate DNA while minimizing the degradation of the genetic material. At this temperature, the solubility of DNA in the alcohol decreases, allowing the DNA to aggregate and become visible. Additionally, the cold temperature helps to protect the DNA from enzymatic activity that could lead to its degradation, ensuring a higher yield and better quality of extracted DNA.
