A DNA sequence that is 15 nucleotides long would normally give rise to a polypeptide sequence that would be 5 amino acids long. This is assuming that all the nucleotides in the DNA sequences are strictly coded to form only sense codons and not a single nonsense codon, also called termination codon
A sense codon is a set of three nucleotides also called a triplet, that codes for a particular amino acid. A DNA sequence of 15 nucleotides has 5 codons.
A nonsense or termination codon is one that does not code for any amino acid. There are three nonsense codons found on mRNA, and these are UAA, UAG and UGA. So if the DNA sequence has one of these, then the amino acids in the polypeptide chain will be 4 in number

Answer:
1. You will be unable to smell
3. Your olfactory receptor cells will no longer be able to respond to molecules trapped in the mucus.
Explanation:
The Olfactory receptors are the receptors present in the olfactory neurons which detect different odorants or smell.
The olfactory receptors are embedded in the epithelium or mucous lining of the nose in which one extension of the cell body reaches the epithelium surface and branches into cilia like structures which sense the odour.
If the axons of the olfactory cells are broken then the cells will not be able to respond to the molecules trapped in the mucus and thus no detection of odour. The signal will not be generated in response and thus will not be sent to the brain. Thus, the person will not be able to smell.
Thus, Options-1 and 3 are correct.
Answer:
Metabolism refers to all the chemical reactions in the body, including those that use oxygen and create carbon dioxide. Oxygen and carbon dioxide, therefore, are involved in both respiration and metabolism. Metabolic reactions are sometimes referred to as cellular respiration, which can cause confusion.
