TRANSCRIPTION AND TRANSLATION
... Sometimes point mutations result in a frame-shift mutation. In this case, a single nucleotide is added or deleted to the DNA sequence. This causes a shift in what is called the reading frame. Because DNA is read three bases at a time in a ribosome, an insertion or deletion can cause the wrong amino ...

The Process of Transcription-2
... • The code is “ordered” – The first 2 positions are more important – When lining up with the anticodon of the tRNA, the third position doesn’t bind as tightly, thus a looser match is possible. – Because of this flexibility, a cell doesn’t need 61 different tRNAs (one for each codon). • Bacteria have ...
