Now scientists think they have cracked the code: Insect nerve cells appear to fire in a sequence unique to each smell, says a report in the 14 November issue of Nature.
«The fact that the genetic code can simultaneously write two kinds of information means that many DNA changes that appear to alter protein sequences may actually cause disease by disrupting gene control programs or even both mechanisms simultaneously,» said Stamatoyannopoulos.
The sequence GGAC, code for the bases guanine - guanine - adenine - cytosine, stood out because it appeared with surprising frequency in the unprocessed primary microRNAs.
In 2000, when scientists of the Human Genome Project presented the first rough draft of the sequence of bases, or code letters, in human DNA, the initial results appeared to confirm that the vast majority of the sequence — perhaps 97 percent of its 3.2 billion bases — had no apparent function.
The published P. coatneyi genome assembly14 (accession numbers CP016239 to CP016252 from NCBI) contains several large open reading frames that appear to correspond to coding sequences, especially in the subtelomeric regions.
No genes that produce abnormal proteins were found, but instead the elevated risk appears to come from groups of tightly - linked DNA sequences called «haplotypes» that regulate the expression of protein - coding genes.
