Expert Solution

Possible single-nucleotide replacements and corresponding amino acids by replacing the first nucleotide of codon GGG are shown in the following table.

Possible single-nucleotide replacements by replacing the first nucleotide of codon GGG	Corresponding amino acid
CGG	Arginine
AGG	Arginine
UGG	Tryptophan

Possible single-nucleotide replacements and corresponding amino acids by replacing the second nucleotide of codon GGG are shown in the following table.

Possible single-nucleotide replacements by replacing the second nucleotide of codon GGG	Corresponding amino acid
GCG	Alanine
GAG	Glutamate
GUG	Valine

Possible single-nucleotide replacements and corresponding amino acids by replacing the third nucleotide of codon GGG are shown in the following table.

Possible single-nucleotide replacements by replacing the third nucleotide of codon GGG	Corresponding amino acid
GGC	Glycine
GGA	Glycine
GGU	Glycine

Hence, possible single-nucleotide replacements of the codon GGG are CGG, AGG, UGG, GCG, GAG, GUG, GGC, GGA, and GGU. Their corresponding amino acids are shown in previous tables.

\Match the following descriptions with the corresponding amino acids: This amino acid is responsible for the strength of rhino horns and wood lignin due to the strong hydrophobic interactions between them. Subtle decreases in the serum pH lead to the protonation of this amino acid, which promotes O2 release from hemoglobin. This amino acid is the nucleophile chymotrypsin uses to attack peptide bonds. This amino acid disrupts α-helices because it makes the nearby protein backbone too flexible (and prevents proper...

List the sequence of structures that a single amino acid (initially in a protein molecule that you eat) goes through from the moment it passes your lips to when it ends up in a hepatocyte. Then explain what (if any) chemicals relevant to digestive physiology it is exposed to at each step and what happens to the protein and eventually protein fragments each step of the way.

A single amino acid change in Ras eliminates its ability to hydrolyze GTP even in the presence of a GTPase-activating protein (GAP). Roughly 30% of human cancers have this change in Ras. You have just identified a small molecule that prevents the dimerization of a receptor tyrosine kinase that signals via Ras. Would you expect this molecule to be effective in the treatment of cancers that express this common, mutant form of Ras? Why or why not? (Please give me...

Sickle cell anemia is a genetic disease resulting from a single amino acid substitution in the hemoglobin β chain. This mutation causes hemoglobin to polymerize into strands in the deoxygenated state, leading to the erythrocytes forming a sickled shape. Why does the mutation lead to polymerization and why does this only occur in the deoxygenated state?
