No there is no selective pressure that confers an advantage to those who do taste it.

<h3>What is PTC?</h3>

Despite the fact that PTC isn't found in nature, tasting other bitter substances—many of which are toxins—that do occur naturally has a high correlation with taste sensitivity.

In order to defend themselves from being eaten, plants develop a range of harmful substances. Early humans developed the capacity to distinguish bitter tastes as a safeguard against ingesting dangerous plants. There are roughly 30 genes in humans that produce bitter taste receptors. People may taste a large variety of bitter substances because each receptor can interact with a number of different molecules.

What if a mutation caused a change in the code so the message read GAG instead of GAC? 
How would this affect the protein produc
Anarel [89]

Answer: There will be no effect on the protein produced

Explanation:

According to the genetic code, the triplet codon GAG code for the amino acid, glutamate, while GAC code for aspartate.

Since GAG and GAC code for amino acids with similar properties (aspartate and glutamate are both acidic amino acids due to the extra carboxyl group present in their side chain), the change in nucleotide is still similar to the original, so will result in a different amino acid sequence, but will not alter the function of the protein at all. Thus, this kind of mutation is called silent mutation.

When the codon and anticodon connect.... What does it build ?
ad-work [718]

Answer: A tRNA with the complementary anticodon is attracted to the ribosome and binds to this codon. The tRNA carries the next amino acid in the polypeptide chain. The first tRNA transfers its amino acid to the amino acid on the newly arrived tRNA, and a chemical bond is made between the two amino acids.
