Answer:
elliptical (nearly circular)
Explanation:
According to Kepler's laws of planetary motion, the planets do not revolve around the Sun in exact circular orbits. The path of the planet or any other body in the solar system is elliptical, with the Sun at one of the foci. Though, the eccentricity is not large, so one can say, the path of the planets and the asteroids around the Sun is nearly circular.
Answer:
4 amino acids.
Explanation:
To become translated into protein, a sequence is read in triplets called codons.
Each codon that codes for an amino acid is made up of 3 nucleotides.
Therefore, a sequence of 15 nucleotides would be translated into a polypeptide that is made up of 5 amino acids. (15 divided by 3 = 5)
However, we are told that there is a stop codon at the end of this sequence.
A stop codon is a specialised codon that does not code for an amino acid, but tells the protein machinery that the polypeptide is complete.
Therefore, the polypeptide would have 5-1 amino acids, which corresponds to 4 amino acids.
