In 2016, you paid $600 interest on a car loan. During 2016, you used the car 60% for business and 40% for personal purposes. You are claiming actual expenses on the car. You can only deduct $360 (60% Ã $600) for 2016 on Schedule C or C-EZ. The remaining interest of $240 is a nondeductible personal expense.
A nonsense mutation is a point mutation that introduces a premature stop codon into the part of the gene that encodes a protein. A stop codon is like a period at the end of a sentence: it instructs the ribosome to stop making the protein.
Nonsense Mutations and Suppression. Abstract. A nonsense mutation occurs when a sense codon, one that codes for an amino acid, is changed to one of the chainâtermination codons, UAG, UAA or UGA. A nonsense suppressor can result from a second mutation affecting the translational apparatus. This mutation enables the cell to insert an amino acid in response to the nonsense codon, resulting in a wildâtype or near wildâtype phenotype.
