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.
Answer:
Developed vaccine for rabies virus.
Explanation:
Louise Pasteur was the french chemist and microbiologist who is known for his discoveries of pasteurization, fermentation and vaccination invention.
Pasteur is known for developing a vaccine for rabies and anthrax. He produced the rabies vaccine by infecting rabbits with rabies virus and harvesting the attenuating virus from nerve tissue of rabbits.
The development of rabies and anthrax vaccine by Pasteur helped in saving the lives of many people. Therefore his work with rabies produced vaccine for the deadly rabies virus.
