⦁ Original: ATTTGAGCCMutated: ATTGAGCC. This is an example of what kind of mutation?
Please ASAP. Thank you. How does the mutation change/affect the structure of the Hb heterotetramer (ie how is quaternary protein structure affected)?
Price et al. [(1999). J. Bacteriol. 181:2358–2362] conducteda genetic study of the toxin transport protein (PA) of Bacillusanthracis, the bacterium that causes anthrax in humans. Withinthe 2294-nucleotide gene in 26 strains they identified five pointmutations—two missense and three synonyms—among differentisolates. Necropsy samples from an anthrax outbreak in 1979revealed a novel missense mutation and five unique nucleotidechanges among ten victims. The authors concluded that thesedata indicate little or no horizontal transfer between differentB. anthracis strains. Question: Which types of nucleotide changes (missense or synonyms)cause amino acid changes?

Cytosine deaminationoccurs ~100 cytosinesper genome per day in a human genome. Eukaryotic cells also contain residues of 5’-methylcytosine, which is involved in regulating gene transcription rates. Mutation of 5’-methylcytosine by deaminationconverts it to thymine. This presents the cell with a much more severe problem than normal cytosine deaminationof cytosine to uracil. Why?
Steroids, carbohydrates, and phospholipidsare encoded by different types of genes thanare proteins.
