A spectrophotometer can be used to know if a sample is DNA or RNA.

DNA has an absorbance maximaat 260nm, whereas RNA has an absorbance maxima at 280nm.

By looking at which one of these two wavelengths the sample is more excited, one can determine if the sample is DNA or RNA.

How can one locate the nucleotide sequence within a given DNA or RNA sample?

To locate the nucleotide sequence within a DNA or RNA sample, one can use a technique called DNA sequencing. This process involves determining the order of nucleotides in the sample, which can be done using various methods such as Sanger sequencing or next-generation sequencing technologies. These techniques allow researchers to read the sequence of nucleotides in the DNA or RNA sample, providing valuable information for genetic analysis and research.
