Describe the structure and functions of the portions of eukaryotic dna that do not encode protein or rna.

A section of DNA that is not expressed in the gene product is called intron. The final messenger RNA molecule is called exon. Eukaryotic cells have the enzyme to cut off the intron section to produce a continuous strand of mRNA so that protein synthesis can occur. Prokaryotic cells can express the information to produce protein directly as the mRNA does not contain intron.

The majority of DNA is made of introns, which don't code for proteins or RNA. Eukaryotic cells comprise of a bigger number of introns than prokaryotic cells. They appear as redundant DNA. 
Straightforward grouping DNA comprises of short, rehashed successions. They have less than fifteen nucleotides, yet it can be rehashed the same number of times as it needs. This makes up three percent of the human genome. Situated at the chromosomal telomeres and centromeres, it most likely has an influence in DNA and chromosomes
