Thename of the aminoacyl-tRNA is usually abbre-viated to fMet-tRNA f .The initiator tRNA gains its modified aminoacid in a two-stage reaction. First, it is chargedwith the amino acid to generate Met-tRNA f ;and then the formylation reaction shown in FIGURE 8.12 blocks the free NH 2 group.
Here's how this might work with multiplication facts. You can make a multiplication table. Since 1 times any number is just that number, we can leave the 1's off. Multiplying a number on the left by a number on the top gives you the number (product) where the row (across) meets the column (down).
Thus commutative principle for multiplication shows that the order does not matter and 3 X 4 = 4 x 3 or the general form: (A)(B)$\equiv$(B)(A). * * * * * * * * * * | * * * * * * * * * * * * | * * * * * * * * * * * * | * *.
