1. Exogenous Causes. Dry Skin is the most common and obvious cause of itchy soles of the feet. The most likely cause is a lack of moisture in the skin. This affects the elderly more than the younger members of the population and it is found more frequently during the colder winter months.
In molecular genetics, an open reading frame (ORF) is the part of a reading frame that has the potential to code for a protein or peptide. An ORF is a continuous stretch of codons beginning with a start codon (usually AUG) and ending with a stop codon (usually UAA, UAG or UGA). An AUG codon within the ORF (not necessarily the first) may indicate where translation starts.
transcription-control region. the cis-acting DNA sequences regulating transcription of a specific gene. transcription factor (TF). a general term for any protein, other than RNA polymerase, required to initiate or regulate transcription in eukaryotic cells.eneral TFs are involved in the formation of the transcription-preinitiation complexes near the start site and are required for transcription of all genes; specific TFs stimulate (activators) or inhibit (suppressors) transcription of particular genes by binding to their regulatory sequences. nested set transcription.
