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.
Assignment # 1. Probability. 1. Open Reading Frames: Assume that the nucleotides A, G, T, C occur with equal probaÂ­. bility (and independently) along a segment of DNA. (a) From the genetic code calculate the probabilityps that a randomly chosen triplet of bases. corresponds to a stop signal. (b) What is the probability for an open reading frame (ORF) of length N, i.e. a sequence of N non-stop triplets followed by a stop codon? (c) The genome of E-coli has roughly 5Ã 106 bases per strand, and is in the form of a closed loop.
