The mutation resulting in sickle cell disease changes one base pair of dna so that a codon now codes for a different amino acid,

iogann1982 [59]

The mutation resulting in sickle cell disease changes one base pair of DNA so that a codon now codes for a different amino acid, making it an example of a missense mutation. Missense mutation is the mutation characterized with <span>changes in one base pair so that the whole amino acid is changed.</span>

A new mutation arises in one person on the island of Kiribati (human population size 100,000). Assuming this particular mutation

tatuchka [14]

Answer:

0.999999 ≈ 1

Explanation:

In a population ( N ) there is the presence of 2N alleles in the population also chance of fixation can be expressed as ; 1/ 2N

Therefore the probability that the mutation will be lost due to genetic drift

= 2N - 1 / 2N ---- ( 1 )

given that ; N = 100,000

back to equation 1

P ( losing mutation due to genetic drift ) = ((2*100,000) - 1 )) / ( 2* 100,000 )

= ( 200,000 - 1 ) / 200,000

= 0.999999 ≈ 1

Example 1: Two different enzymes are able to catalyze the same reaction, A → B. They both have the same Vmax, but differ their K

luda_lava [24]

Answer: (a) = 0.022mmoles/minute; (b) = 0.00022mmoles/minute; (c) = 0.022mmoles/minute

Explanation:

The Michaelis- Menten equation is used to show the relationship between substrate concentration and reaction rate.

The equation is Vo = Vmax[S]/(Km + [S]

where Vo is the initial velocity, Vmax is the maximum velocity, [S] is the substrate concentration, Km is the Michaelis constant.

(a) For enzyme 1; Vo = 0.002mmoles/minute, Vmax = ?, [S] = 0.1mM, Km =1.0mM; making Vmax subject of the formula;

Vmax = Vo * (Km + [S])/ [S]

Vmax = 0.002*(1.0 + 0.1)/ 0.1

Vmax = 0.022mmoles/minute (Vmax for Enzyme 1&2)

(b) Vo = Vmax[S]/(Km + [S]

Vo = 0.022 * 0.1/(10+0.1) = 0.00022mmoles/minute

Vo = 0.022*1000/(1.0+1000) = 0.022mmoles/minute
