Alex

Answer: B. Melting temperatures of primer should be between 55-80 degree Celsius.

Explanation:

Bacause the melting temperature controls the binding of the primers to your template DNA. At melting temperature 50% of the primer molecules are bound to their corresponding target sequence. If the difference in melting temperature between the two primers is too high, it might be difficult to find experimental conditions where both primers can bind to their target.

Elis [28]

Neurotransmitter has to be consumed in the diet is not the criteria for neurotransmitter. So the correct option is a.

A neuron releases a signaling chemical called a neurotransmitter across a synaptic gap to influence another cell. Any major body component or target cell that receives the signal may be another neuron, but it could also be a gland or muscle cell. These signals enable you to move your limbs, experience sensations, maintain heartbeat, as well as receive and process all the information your body receives from other internal body parts and your environment.

These signals enable you to move your limbs, experience sensations, maintain heartbeat, as well as receive and process all the information your body receives from other internal body parts and your environment.

The axon terminal, a component of the neuron, is where neurotransmitters are found. They are kept inside synaptic vesicles, which have thin walls. Numerous thousands of neurotransmitter molecules can fit inside each vesicle.
