O allele 60 + 60+30 = 150
o allele 
30 + 10+10 = 50
O allele frequency = 150/200 = 0.75
Thus, the O allele frequency is 3/4 or 0.75
o allele frequency = 50/200 = 0.25
The o allele frequency is 1/4 or 0.25

PilotLPTM [1.2K]

The size of actual bed is 75 inches

Explanation:

Scale refers to the ratio of the original dimension to the dimension on paper (miniaturised dimension). Since it is a ratio, it has no dimension.

Scale= original dimension/miniaturised dimension

Given that scale is 1:25

It means that every 1 inch on paper would correspond to 25 inches in reality.

The length of the model bed= 3 inches

Hence, the length of the original bed is 25*3 = 75 inches

∴ Length of the actual bed of the student is 75 inches.

Answer:

Tertiary structure is formed by the folding of the secondary structure sheets or helices into one another. The tertiary structure of protein is the geometric shape of the protein. It usually has a polypeptide chain as a backbone, with one or more secondary structures. The tertiary structure is determined by the interactions and bonding of the amino acid side chains in the protein.

The tertiary structure is determined by the interactions and bonding of the amino acid side chains in the protein.Quaternary structure results from folded amino-acid chains in tertiary structures interacting further with each other to give rise to a functional protein such as hemoglobin or DNA polymerase.
