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).
For instance, suppose your number is â6, and you're multiplying. The identity is one, and the inverse is â1/6, because (â6)(â1/6) = 1. You also know (if you've done any equation solving) that you can do anything you want to an equation, as long as you do the same thing to both sides. This is the property of equality.
