A mutation is a permanent change in the sequence of nucleotide bases in a cell's DNA. Most mutations happen during DNA replication, but their effects are not seen until transcription and translation. Even a small mutation that changes a single nucleotide can have a major impact on the resulting proteins that are made in the cell. с The table following the amino acid chart lists a segment of a normal gene. Type in the corresponding mRNA strand and the amino...

The strain of XDR-TB that the young man had above was studied further by analyzing the DNA of the Mycobacterium tuberculosis. The investigators particularly looked at the gene for the protein targeted by the antibiotic rifampin. MDR-TB and XDR-TB are resistant to rifampin. Q1. What is the protein target for rifampin in the bacterial cells? What biological process does the antibiotic stop? (see notes). The following results were obtained from the young man's M. tuberculosis for the DNA sequence of...

1. You are a scientist studying a rare heritable disease, Pitt-Hopkins syndrome. This disease is caused by mutations in the basic helix-loop-helix transcription factor, TCF4. You sequence the TCF4 gene in your patients and identify several sequence variants. a) The TCF4 coding region and sites of mutations for several patients are shown here (lines between codons indicate the open reading frame). For each patient, identify the impact of the mutation on the coding sequence (1 mark each) and the likely...
