Why are the two strands of the double helix "perfect and specific compliments"?
77julia77 [94]
Because for the strands to form a double helix the base pairs have to match perfectly (adenine with thymine and cytosine with guanine) in DNA , and if a strand of RNA is paired with a split strand of DNA it goes adenine with uracil and cytosine with guanine (uracil replaces thymine)

The binding of Ach to its muscuranic receptors indirectly affects the permeability of _____ channels which can produce hyperpola
MArishka [77]

Answer:

The binding of ACh to the muscarinic receptor indirectly affects the permeability of K⁺channels. This can produce hyper polarization in some organs if channels are opened, and depolarization in others if channels are closed.

Explanation:

For example, in the heart it is the beta-gamma compound that fixes to the K+ channels of heart muscle and sources them to exposed. This leads to K+ dispersion out of the cell and the cell converts into hyper polarized consequential in a reduction in heart rate. In contrast, in smooth muscle of the stomach the alpha sub unit fixes to K+ channels producing them to close. This decreases the external diffusion of K+ and the cell converts depolarized ensuing in smooth muscle contraction.
