Answer 1

DNA profiling and fingerprinting can be done and database can be maintained because of computer and internet.

Explanation:

DNA profiling is the study of DNA and recording the number and types of genes that are present in particular loci of the DNA, which is particular for different individuals, and are recorded for future research and scientific purposes. While DNA finger printing is the unique identity of a particular individual which is 100% proof of a person's identity, and is determined by action of electrophoresis in AgarAgar gel.

These are huge amounts of data that needs to be stored and recorded for future purposes. But storing these data in pen and paper is practically impossible. So development of computer, and the internet supply has actually made it much simpler to record them and store, and to find them in any time without hussle.

Answer 2

The development of DNA profiling as well as the creation of national databases for both DNA profiling  and fingerprinting depended on the invention of luminol.

Explanation:

• The importance of luminol was highlighted by a scientist named walter specht in the year 1937
• Luminol (C8H7N3O2) is a chemical that exhibits blue glow, when mixed with an appropriate oxidizing agent.
• Luminol is a light producing chemical that exhibits a blue light when mixed with an oxidizing agent  
• luminol is used to detect the traces of blood during a criminal investigation.It is also used in  cellular assays to detect copper, iron, cyanides, and specific proteins through the method of  western blotting
