between gene and protein was first articulated by Beadle & Tatum, who proposed the one-gene, one-enzyme hypothesis - which of the following statements contradicts this hypothesis? O Sickle-cell anemia results in defective hemoglobin. Two enzymes are able to metabolize the same reaction. Alkaptonuria results when individuals lack a single enzyme involved in the catalysis of homogentisic acid. A mutation in a single gene can result in a defective protein. A single antibody gene can code for different related proteins, depending on the splicing that takes place post-transcriptionally.

Similar questions

In each case, these are enzymes that catalyze thesame reaction in different species. The question is: are they related or not? i.e. Are the structures essentially the same? Often you can get similar reactions from proteins thatevolved from a common ancestor (e.g., trypsin and chymotrypsin). Sometimes the samereaction can be catalyzed by proteins with very different evolutionary origins and with verydifferent structures (e.g., trypsin and subtilisin). Your job is to decide if these proteins have fundamentally different folds or if they have basically the same fold. Briefly justify your answer.1. Aminopeptidases from a mammal (PR1A) and the malaria parasite (PR1B)2. Bisphosphoglycerate mutase from a mammal (PR2A) and the toxoplasma parasite(PR2B)
Failure of anti-oxidant function results in the hydroxylation of an aromatic acid of Enzyme Z and its activation, so that it degrades protoporphyrin to porphyrin, an unstable product. When hit by light, this product further degrades to form a compound responsible for the lesions and excruciating pain the man suffers. The mutation also affected an amino acid at the N-terminal of Enzyme X. Sequencing of the first seven (7) amino acids at the N-terminal of the normal enzyme gave the following sequence: trp-arg-asp-leu-ser-gly-his When the cDNA was sequenced by the Sanger method utilizing ddCTP, the following products were obtained: Tetranucleotide Hexanucleotide Nonanucleotide Decanucleotide Dodenucleotide Octadecanucleotide Nonadecanucleotide 21-nucleotide The mutation involved the 19th bases of the template strand of the peptide. A comparison of the electrophoretic profile of the normal peptide (N) and mutant peptide (M) is shown below. The (+) electrode is situated at the bottom. pH…

When performing his experiments on protein refolding, Christian Anfinsen obtained a quite different result when reduced ribonuclease was reoxidized while it was still in 8 M urea and the preparation was then dialyzed to remove the urea. Ribonuclease reoxidized in this way had only 1% of the enzymatic activity of the native protein. Why were the outcomes so different when reduced ribonuclease was reoxidized in the presence and absence of urea?
Analyse and interpret the SCAM data in Fig. 1, and make a table (remember to include a legend) to indicate where each amino acid is located (cytoplasm, membrane, periplasm).
Which of the following could create different versions of an enzyme? (Select all that apply) Note: by "versions" we mean isoforms with similarity but also some differences in their polypeptide sequence Group of answer choices reciprocal regulation allosteric activation substrate concentration a gene is duplicated and the 2 copies evolve different changes over time alternative splicing
Explain how these mechanisms affect protein diversity.
Small molecules are used as inhibitors of protein action - as drugs. They most often do this by blocking the active site within the protein. Potential drugs can be screened computationally to determine if they are strongly bound to the protein. Figure 1 shows a possible conformation of a candidate drug molecule, 4-bromo-2- carboxymethylamide-pyrrole (abbreviation: BCMAP) at the active site of a protein (abbreviation: PR). Figure 2 shows the full protein structure whilst figure 3 shows a known inhibitor of the protein at the site, overlayed with another calculated conformer of BCMAP. (a) Explain what types of interactions, both intermolecular and intramolecular, that a molecular mechanics forcefield must be able to describe in order to be able to accurately determine the geometry of BCMAP in the protein. Identify which interactions will be the most important to describe accurately. Figure 1.4-bromo-2-carboxymethylamide-pyrrole (BCMAP) (C, N, O, and Br atoms in yellow, blue, red, and…

High concentrations of sulfa drugs denature all proteins Low concentrations of this sulfa drug are enough to permanently bind nucleic acids High concentrations of this sulfa drug allow binding to the active site of the enzyme permanently denaturing it by inducing oxygen toxicity
A lipase enzyme has been isolated from a bacterium with a strong red color, found in industrial waste from a fishing company. This enzyme has great potential for elaboration of degreasers for industrial use as it can work at a wide range of temperature (between 4 ° and 80 ° C). However, it is estimated that its purity for industrial purposes is only 35% since it is contaminated with a low molecular weight protein that binds the smallest red pigment peptides and salts product of the purification process 1- Propose a methodology to increase the degree of purity of this enzyme, eliminatingsmall proteins and color.2- How it is ensured that the degree of purity of the enzyme has increased.
