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.
1 We can start translating, or reading, the DNA from the first letter, 'a,' which would be referred to as the first reading frame. 2  Or we can start reading from the second letter, 'c,' which is the second reading frame.Or we can start reading from the third letter, 't,' which is the third reading frame. The reading frame affects which protein is made.In the example below, the upper case letters represent amino acids that are coded by the three letters above and to the left of them. We can start translating, or reading, the DNA from the first letter, 'a,' which would be referred to as the first reading frame. 2  Or we can start reading from the second letter, 'c,' which is the second reading frame.
