He then asked news organizations to tally up the number of Americans killed through terrorist attacks in the last decade and compare it with the number of Americans who have died in gun violence.
In molecular biology, a reading frame is a way of dividing the sequence of nucleotides in a nucleic acid (DNA or RNA) molecule into a set of consecutive, non-overlapping triplets. Where these triplets equate to amino acids or stop signals during translation, they are called codons.
In other cases, mutations alter the way a gene is read through either the insertion or the deletion of a single base. In these so-called frameshift mutations, entire proteins are altered as a result of the deletion or insertion.
