D. A hormonal signaling pathway between endocrine glands and tissues

Explanation:

Our body is formed by a complex organization of various tissue, organs and organ-systems. It has specific mechanisms to regulate the functions of all its cell, tissue and organs. Besides neural system, the endocrine system also plays a crucial role in the regulation of body functions. This system consists of many pathways that originate from the hormone secreting glands called endocrine glands and reaches to the target cell or tissue or organ. These pathways are collectively named as the endocrine axis.

kirill [66]

Answer:

<h2>A site for the exit of the diphosphates removed from the nucleotide triphosphates.</h2>

Explanation:

Transcription occurs in three steps, i) initiation, ii) elongation, and iii) termination.

Elongation: during elongation , the RNA polymerase add new nucleotides in the growing chain of RNA molecule until it encounter terminator factor, or until it terminate transcription. RNA polymerase has three prominent channels, i) channel for entry of DNA template strand, ii) channel for exit of DNA strand and iii) channel for exit of newly synthesized RNA molecule. There are lots of other enzymes which helps in transcription.
