Answer:
D) Silent mutation on second codon, third amino acid changed from ILE to ASN.
Explanation:
Silent mutations are usually point mutation where you change one nucleotide. Since, the nucleotide changed is the third position, it does not affect the protein being manufactured (it will still put the amino acid Ala) [look up the codon redundancy on youtub.e to understand how awesome nature is!]
On the other hand, the other mutation introduced is Missense mutation where a different Amino acid is added due to change in codon (goes from ILE to ASN).
Answer:
Thus, the minimum number of photons per second is 77.34
Explanation:
Light intensity, =
Pupil has a diameter, d = 8.5 mm
= 8.5 x m
Radius of the eye, r = 4.25 x m
∴ Area of the eye, A =
=
=
Let be the minimum number of photons.
Therefore, =
x A
= x
= W
Thus the minimum number of photons is given by
where E =
=
=
Therefore, =
= 77.34 photons per second
Thus, the minimum number of photons per second is 77.34
