The following DNA sequence occurs in the nontemplate strand of a structural gene in bacterium (the promoter sequence is located to the left but is not shown): 5 -GAATGTCAGAACTGCCATGCTTCATATGAATAGACCTCTAG-3 What is the ribonucleotide sequence of mRNA molecule that is transcribed from this piece of DNA?
Non-coding DNA does not encode protein sequences. This does not mean that Non-coding DNA has no purpose or is junk. Some of it is clearly functional and is transcribed into fRNA molecules. Much of it has no known function, but claims that it ha...
