One gene\'s-worth of information can range from 100 1 million base pairs of DNA.

Question

One gene's-worth of information can range from 100 1 million base pairs of DNA. The average gene is about 1000 long and there are about 3 billion base pair in the human genome. However, only 2% base pairs points) of the human genome is comprised of genes. what makes up the rest? One gene's-worth of information can range from 100 1 million base pairs of DNA.

Explanation / Answer

Yes only 2% of genome codes for some proteins in eukaryotes and the rest of 98% doesn't code for any functional proteins. This is called non-coding DNA. In lay terms it is called junk DNA. It comprises of introns, cis- trans regulatory elements, pesudogenes, repeat sequences, transposons, viral elements, telomeres etc. So, it is not correct to say junk DNA. The non-coding DNA does have functions other than secreting proteins, such as regulation of transcription, DNA stability etc. Some of the non-coding DNAs code for RNA but they won't get translated in to protein. These RNAs acts as regulators of gene transcription (ex: micro RNAs).
