Trypanosomes have a novel post-transcriptional process for editing mitochondrial rna. in this form of rna editing, several uracil bases are inserted at specific locations in an mrna (e. g., for purposes of shifting the reading frame into correct position). the insertions are directed by short guide rnas (grnas) that encode editing "instructions" in the form of complementary base-pairing sequences. which enzyme involved in this process catalyzes the addition of uracil (u) bases to the mrna?

it's     c       this is a cell (b) with a nucleus (c) containing dna (a). the dna is organized into chromosomes (d). a section of the chromosome that codes for a trait is called a gene (e).

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
