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. With a nonsense mutation, the new nucleotide changes a codon that specified an amino acid to one of the STOP codons (TAA, TAG, or TGA). Therefore, translation of the messenger RNA transcribed from this mutant gene will stop prematurely.onsense mutations.
