Answer:
330
Explanation:
A codon is the sequence of three nucleotides on mRNA that refers for particular amino acid during translation (protein synthesis) process. The four nucleotides arrange themselves in various combinations to produce different codons. The tRNA with corresponding anticodon attach the particular amino acid to polypeptide chain during translation.
Remember there is always a stop (UAA) and start codon (AUG) for the synthesis of polypeptide and stop codon does not contribute for any amino acid. It just terminate the polypeptide chain synthesis. We know that a codon is made up of three nucleotide so our calculation will be.
993-stop codon =990
990/3=330
So that's why 330 amino acid will be incorporated in the polypeptide chain.
Peristalsis is the name for the waves of contractions that propel substance s along a tract. It is a series of wave-like contractions that moves food to different processing stations in the gastrointestinal tract and starts in the esophagus when the boluses of food are swallowed. The wave motion is produced by the longitudinal smooth muscles that line up the esophagus, stomach, small intestines and the colon and is triggered by presence of food.
