What is the structure and function of nucleic acids?

Nucleic acids are long chainlike molecules composed of a series of nearly identical building blocks called nucleotides. The functions of nucleic acids have to do with the storage and expression of genetic information

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added
