- Beadle and Tatum proposed the one gene-one enzyme concept - This hypothesis can now be restated in which of the following ways? A given sequence of DNA nucleotides contains information to make one enzyme Each gene contains information to make one protein, one lipid and one carbohydrate Each gene is actually an enzyme that catalyzes the production of one protein Each polypeptide is the result of the activity of one enzymeThe One Gene One Enzyme Hypothesis (Beadle and Tatum, 1941) stated that each gene codes for a single enzyme. Summarize the advancements that have made the One Gene One Enzyme Hypothesis obsolete.What effects do mutations have on organisms? O All mutations are harmful because they disrupt protein function or gene regulation % All mutations are beneficial to organisms because they improve protein function or gene regulation All mutations have no effect on organisms, because they do not significantly affect protein function or gene regulation Some mutations are harmful, some are beneficial, and some have no effect on the organism
- In what order does the genetic information flow in living organisms? Choose all that are true. genetic information can be rewritten from protein to DNA genetic information can be translated from RNA to protein genetic information can be rewritten from DNA to RNA genetic information can be rewritten from protein to RNA genetic information can be rewritten from RNA to DNA1:58 l 5GE Done 18 of 23 4 of 12 A team of scientists are developing a method to measure ATP levels in the cell instantaneously. This would allow scientists to take immediate measurements of ATP and determine where ATP is localized in the cell. Which of the following statements best explains the benefit of measuring ATP in a cell instantaneously? Measuring the levels of ATP will allow A scientists to locate mutations within the nucleus. Measuring the levels of ATP will allow scientists to locate where energy is used for cellular activities. Measuring the levels of ATP will allow scientists to determine if the cell is undergoing meiosis. Measuring the levels of ATP will allow D scientists to determine if the cell is a prokaryote or eukaryote. Submit IIHow could insulin deficiency in a patient potentially affect the flow of information from gene to protein?
- . Describe how missense mutations were used to showthat genes determine the amino acid sequences ofproteinsSuppose you carry out genomic, transcriptomic, and proteomicstudies on a single tissue. What type of information would youobtain from each sort of study? For understanding physiology,what are the uses and shortcomings of each type of information?. The physicist Stephen Hawking, famous for his theories about black holes, has lived past the age of 70 withamyotrophic lateral sclerosis (ALS), a paralyzing neurodegenerative disease that is usually fatal at a muchyounger age. Recently, geneticists discovered that amajor cause of ALS is the unusual expansion of ahexanucleotide repeat (5′-GGGGCC-3′) that lieswithin a gene called C9ORF72, at a location outside ofthe gene’s open reading frame (ORF). A single expanded allele is sufficient to cause ALS, but the reasonthe disease allele is dominant remains unclear. Someexperimental results support the theory that the allelemakes a toxic RNA containing the expanded repeat. Ifthis theory is correct, in what ways is the mutant ALScausing allele similar to the mutant allele that causesHuntington disease? In what ways is it similar to themutant allele that causes fragile X syndrome?

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.
