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).
The inverse operation of the multiplication is the division. For example, since 4 multiplied by 3 equals 12, then 12 divided by 3 equals 4. Multiplication by 3, followed by division by 3, yields the original number (since the division of a number other than 0 by itself equals 1).
