Answer:

Initiation. RNA polymerase binds to a sequence of DNA called the promoter, found near the beginning of a gene. Each gene has its own promoter. Once bound, RNA polymerase separates the DNA strands, providing the single-stranded template needed for transcription.

g Indium has two naturally occurring isotopes: 113In with an atomic weight of 112.904 amu, and 115In with an atomic weight of 11
aleksandrvk [35]

Answer:

Fraction-of-occurrences of 115In isotope = 0.957

Explanation:

As we know  weight of 113 In  isotope is equal to the sum of product of fraction-of-occurrences of two constituents isotopes and their atomic weight

^{115}In_w = f_{113}*A_{113} + f_{115}*A_{115} ------(1)

As we know sum of fraction-of-occurrences of two constituents isotopes is equal to one.

f_{113} + f_{115} = 1\\f_{113} = 1- f_{115}---------(2)

Substituting the given values in equation 1, we get

^{115}In_w = f_{113}*A_{113} + f_{115}*A_{115}\\114.818 = (1 - f_{115}) * 112.904 + f_{115} * 114.904\\f_{115} = 0.957

Substituting this value in equation 2 we get -

f_{113} = 1- f_{115}\\f_{113} =  1- 0.957 \\f_{113} = 0.043
