Random mutations only very rarely result in changes in a protein that improve its usefulness for the cell, yet useful mutations are selected in evolution. Because these changes are so rare, for each useful mutation there are innumerable mutations that lead to either no improvement or inactive proteins. Why, then, do cells not contain millions of proteins that are of no use?

You are a molecular biologist studying a defective human protein that is known to be a cause of a rare cancer. You isolate the suspected protein from a person with this cancer and compare it to the same protein in a person without the cancer. You discover that the protein isolated from the cancer patient is slightly smaller in size when compared to the protein from the unaffected patient. Furthermore, you discover that the protein from the cancer patient differs in almost every amino acid starting after the 23rd amino acid. What is the likely explanation?

Three proteins, A, B, C were found to evolve from an ancestral protein with a critical amino acid, X change in the sequence of the progenies. The following amino acid change was observed, and studies show that only one base in the gene for the codon was altered as the ancestral protein evolved. The following changes were observed: Protein A: X → val Protein B: X -→ gly Protein C: X → glu Which of the following is most likely amino acid X? A. Lys B. Ser C. Leu D. ala O E. cannot be determined
Based on our modern understanding, what revisions are necessary to the original one-gene / one-enzyme hypothesis? (Check all that apply.) Alternative splicing allows one gene to encode multiple polypeptides. Some genes encode RNAs, not enzymes. Some genes encode lipids, not enzymes. Some genes encode polypeptides that are not enzymes, such as structural proteins. Proteins as functional units may be composed of several polypeptides, so genes may encode just one polypeptide within a larger protein. Enzymes are not encoded by genes after all — they are constructed through separate biochemical processes.
Some bacteria might be able to respond to environmental stress by increasing the rate at which mutations occur during cell division. How might this be accomplished? Do you think there would be an evolutionary advantage of this ability? Explain.
As discussed, the overall rate of mutations in humans is estimated to be about 1 × 10−8 mutations per base pair per generation. How many new mutations would you expect each person to carry, on average, based on this mutation rate? Other studies have estimated that each person carries about 100 new loss-of-function mutations. How does this number compare with your estimate of the number of mutations based on the mutation rate? What might account for any differences?
You are studying a mutation in mice, which acts dominantly. Mice that have only one copy of the allele carrying this mutation have a kinky tail phenotype. You identify the gene that the mutation affects and find that the codon that encodes the second amino acid in the predicted protein has been mutated to a stop codon. Would you characterize this mutation as a loss-of-function or a gain-of-function and what specific subtype (hypermorphic, antimorphic, etc. ) within these categories? Explain your reasoning.”
Suppose that a gene has a mutation that changes one nucleotide. Compared to the protein produced from the non-mutated gene, the protein produced from this mutated gene has one different amino acid. This newly altered protein provides enhanced resistance to tetracycline (an antibiotic). This type of mutation would be classified as a
Many aspects of gene function can be nicely explained with the one- gene-one-enzyme hypothesis, which states that a gene controls the production of an enzyme. Which of the following findings about gene expression, though, requires an expansion of this simple concept? Non-enzyme proteins are made from genes too. Some genes code for RNA molecules only. Enzymes composed of different polypeptides are coded for by more than one gene. a and c, but not b a, b, and c
Galactosemia is a metabolic disorder characterized by the inability to metabolize the sugar galactose. People with galactosemia suffer from liver, kidney, and brain damage among other symptoms. A gene mutation underlying galactosemia was identified by sequencing the genome of a person with galactosemia. What additional evidence would support the hypothesis that the mutation in the candidate gene causes the disease?
Is the following statement true or false?Why? “The flow of genetic information in the cell is alwaysDNA -> RNA -> protein.”
Suppose that a mutation resulted in a tapeworm that did not have hooks. Assuming this tapeworm was a human parasite, what is the most likely explanation of the effect might this have? The tapeworm would spread throughout the human body. The tapeworm would complete its entire life cycle inside the human host. The tapeworm would not remain in the digestive tract very long. The tapeworm would not be able to enter the human body. The tapeworm would reproduce more to compensate for a lack of hooks.
