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 mutation: A mutation (a change) in a base in the DNA that prematurely stops the translation (reading) of messenger RNA (mRNA) resulting in a polypeptide chain that ends prematurely and a protein product that is truncated (abbreviated) and incomplete and usually nonfunctional.ne of them comes normally at the end of each polypeptide. A nonsense codon is a stop codon which is out of place. Catching such a defective messenger RNA (mRNA) before a truncated and potentially harmful protein is synthesized is the job of what is called the nonsense-mediated mRNA decay (NMD) pathway.
