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).
In arithmetic, the additive identity is. . This means that you can add 0 to any number... and it keeps its identity! The number stays the same! Let's look at the number 5. Anyway we try to add 0 to it, the 5 just keeps coming back as the answer. Go ahead and try it with any number you can thing of...
