Which of the following components is involved in the initiation of transcription?
primer
origin
promoter
start codon

Promoter.

Explanation:

Transcription may be defined as the process of generation of the RNA molecule from the DNA template. The process of transcription includes initiation, elongation and termination.

Promoter may be defined as the region of DNA that are located in the upstream region. The initiation of transcription requires the promoter region that allows the binding of RNA polymerase at the initiation site.

Thus, the correct answer is option (3).

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.
