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.
Frameshift mutation (illustration). This type of mutation occurs when the addition or loss of DNA bases changes a geneâs reading frame. A reading frame consists of groups of 3 bases that each code for one amino acid.A frameshift mutation shifts the grouping of these bases and changes the code for amino acids.his type of mutation occurs when the addition or loss of DNA bases changes a geneâs reading frame.
