These segments are often called 'junk DNA' but we are learning that they are not really 'junk' as once was thought. The human genome is a genetic jungle full of sequences of "freeloaders," "parasites," "hitchhikers," "ancient viral invaders," and "evolutionary fossils" that are all competing for space on the DNA molecule.
The ENCODE project has looked deeper into this "junk DNA" than ever before. And junk it is not: According to more than 30 research papers published in a number of journals including Science and Nature, at least 80 percent of the genome is biologically active, with much non-protein-coding DNA regulating nearby genes in a complex dance of influence.
The conservation of "junk DNA" sequences in diverse genomes suggests that they have important functions.
no because the introns have no function in protein synthesis
In Biotechnology, vectors are used to transport and insert specific DNA sequences into target genomes.

the significance of noncoding DNA to DNA identification is to drive main evoloutionary changes like the developement of unique human parts

A noncoding portion of DNA is called an intron, and is composed of codons that will eventually be removed after transcription when the final mature strand of mRNA is produced.
No; genomes are made from DNA or RNA, which are nucleic acids,
Introns.

Genomics is the study and analysis of DNA sequencing and fine-scale genetic mapping. It examines the sequence, assembly, function and structure of genomes.
