The answer is D. Cellular respiration
The chart very nicely lays out the amino acid each codon corresponds to. You're looking for "trp" in the chart, which only appears once, beside the UGG codon. Therefore, only one codon codes for tryptophan.
In recent molecular genetic studies, genes associated with the neurotransmitter Dopamine have been linked to ADHD.
ADHD stands for Attention Deficit Hyperactivity Disorder. People with ADHD have a hard time focusing on tasks. Scientists have found that the low levels of dopamine in the brain are associated with the symptoms of ADHD. It is because the neurons in the brain have a high amount of protein called the dopamine transporters. These proteins block the dopamine from passing between the neurons. This decreases the effect of dopamine.
<span>The function of a cell wall has the same
function of the cell membrane; it protects the cell. Cell wall is made up of cellulose
that is only present in plant cells. Cellulose is a sugar that has a sheet like
structural carbohydrate. It is rigid that is used for support and provides protection
to the plant cell from damage. They cannot be dissolved in water. An example is
if you eat food that contains mostly of leaves. You will observe that you will
eliminate the same material as when you it. That is because our human body does
not have the enzyme that dissolves the cellulose.</span>
