Concept explainers
Interpretation:
The fact which determines the significance of a change in the identity of an amino acid in a protein should be determined.
Concept Introduction:
A base is nitrogen containing heterocyclic compound which is found in DNA and RNA.
Gene is the biological unit of heredity which holds the information to build and maintain their cells and pass genetic traits to offspring. In cells, a gene is a portion of DNA.
Amino acids are the molecules which containing an
Amino acids are the basic structural building units of protein and other
Proteins are organic nitrogenous compounds formed of Carbon, Hydrogen, Oxygen and Nitrogen. They are the

- Indicate all the possible sequences for a tripeptide containing alanine, glutamine, and methionine; use the standard abbreviation for each amino acid (Ala, Gln, Met).arrow_forwardidentify the interaction that may be produced between the side chain of amino acid residues found at the N-terminus and the C-terminus of the peptide. List all possible peptides that can be formed from the given peptide (use three character/letter abbreviations for each amino acid, i.e., Ala-Gly-Val). NOTE: Any excess will be deducted to the correct answers. Be careful in evaluating your answers.arrow_forwardWhat type of intramolecular interactions can be found between amino acids within proteins to help maintain their native structure?arrow_forward
- Which is the major force responsible for the formation of an α-helix in protein secondary structure?arrow_forwardThere are a total of six different amino acid sequences for a tripeptide containing one molecule each of serine, valine, and glycine. Using three-letter abbreviations for the amino acids, draw the six possible sequences of amino acids.arrow_forwardWhat is meant by a conditional amino acid?arrow_forward
- HOW MANY DIFFERENT PROTEINS CAN BE CONSTRUCTED THAT ARE EXACTLY FOUR AMINO ACIDS LONG? (HINT: THERE ARE 20 POSSIBLE AMINO ACIDS.)arrow_forwardWhat is the difference between a simple protein and a conjugated protein?arrow_forwardA monomeric protein contains 154 amino acids. How many codons code for these amino acids? How many nucleotides?arrow_forward
- In sickle cell anemia, a hereditary disease, there is substitution of one amino acid by another in one of the four polypeptide chains of hemoglobin. In this case are all of the structural levels of the protein modified?arrow_forwardHow is an amino acid sequence (i.e. a protein) made from an RNA sequence?arrow_forwardDescribe the gene and protein defects in phenylketonuria (PKU). How are these defects connected to disease symptoms?arrow_forward
