Diphenyle amine reacts with DNA and liberates inorganic ortho phoshate of Dna. amine group of diphenylamine is combined with DNA before the phosphate group is released from the sugar. By this action DNA solution gets dark blue color which was estimated by using spectrophotometer.
What else can I help you with?
Why do we use lambda DNA used as a marker in DNA extraction?
Lambda DNA is used as a marker in DNA extraction because it serves as a reliable standard for size comparison during gel electrophoresis. Its known fragment sizes allow researchers to estimate the size of the extracted DNA and verify its integrity. Additionally, using a consistent marker like lambda DNA helps ensure reproducibility and accuracy in experimental results. This is particularly useful in applications such as cloning, sequencing, and various molecular biology techniques.
What is the importance of DNA transcrip?
DNA transcrip transcribes the DNA so that RNA may use it and replicate it.
Why was it difficult to use DNA as evidence in a crime pcr was invented?
you need many copies of DNA for DNA fingerprinting
Which is not a reason that scientists use bacterial DNA rather than human DNA in biotechnology?
One reason why scientists may use bacterial DNA over human DNA in biotechnology is because bacterial DNA is often easier and cheaper to manipulate and study given its simpler structure compared to human DNA.
What can you use DNA for in biology?
reproduction
Do scientists use real DNA?
Yes, they do use real DNA.
What does transcriptase use to form DNA?
Reverse transcriptase use mRNA to form DNA. mRNA
When researchers use a molecular clock they can estimate that time since two organizes shared a?
common ancestor by comparing the differences in their DNA sequences. By measuring the rate of mutations in DNA sequences over time, researchers can estimate how long ago two organisms diverged from a common ancestor. This provides insights into the evolutionary history and relationships between different species.
How can you use DNA information?
DNA tells you who or makes up who you are DNA tells you who or makes up who you are
How is the DNA in your brain cells different from the DNA in your heart cells?
They use different DNA codes
Why use chloroform in DNA isolation?
DNA is soluble in chloroform more than water. So we use it.
Does DNA use uracil in its structure?
No, DNA does not use uracil in its structure. Uracil is a nitrogenous base found in RNA, while DNA uses thymine instead.
Use of NaCl in DNA Hydrolysis?
Salt is used to separate DNA.
How would you use DNA in a sentence?
The DNA of a cat is different from that of a human.
What is the importance of DNA transcrip?
DNA transcrip transcribes the DNA so that RNA may use it and replicate it.
Which characteristics do scientists to use to group species?
Scientists use Ancestors and DNA to group DNA.
How do you use the word DNA in a sentence?
every strand of DNA is different is an example use it as a noun
