In the peripheral nervous system, ACh is the neurotransmitter at the neuromuscular junction between the motor nerve and skeletal muscle. Figure 11.3. Distribution of cholinergic cell groups and projections in the rat brain.n the peripheral nervous system, ACh is the neurotransmitter at the neuromuscular junction between the motor nerve and skeletal muscle.

Describe your reasoning. As guanine and cytosine are complementary, another 15% of the nucleotides must have cytosine. The remaining 70% of the nucleotides (100%-30%) must have adenine and thymine in equal proportions (35% each), as they are complementary to each other.f 15% of the nucleotides in a DNA molecule contain guanine, what percentage of the nucleotides having each of the other three bases?
But they all consist of 4 nucleotides 2 made of purine bases which are adenine and guanine and 2 pyrimidine bases which are thymine and cytosine. The purine based nucleotides always pair with their base pair pyrimidine based nucleotide.In DNA Adenine is paired with thymine and guanine pairs with cytosine.here are four nucleotides that make up DNA, each defined by the  nitrogenous bases they contain. They are named adenine, thymine,  guanine and cytosine.
