Foraging Behavior - The Search for Food

Optimizing its foraging behavior

1. When the difference between the energetic benefits of food consumption  and the energetic costs of food gathering is maximized.

2. Animals with optimal foraging strategies will have more available energy with which to survive and reproduce.

The introns in pre-tRNA vary in length from 14 to 60 bases and only single intron is found in each pre-tRNA transcript A pre-tRNA intron is excised in one step  Finally, hydrolysis of GTP and ATP is required to join the two tRNA halves generated by cleavage on either side of the intron.

Splicing of pre-tRNAs is catalyzed by proteins, not by RNAs. The box H/ACA snoRNPs are involved in pseudouridylylation, and box C/D snoRNPs function in 2-O-methylations
