What does gene therapy use and why?

1 answer:

6 0

Gene therapy is designed to introduce genetic material into cells to compensate for abnormal genes or to make a beneficial protein. If a mutated gene causes a necessary protein to be faulty or missing, gene therapy may be able to introduce a normal copy of the gene to restore the function of the protein.

Onsider the chemical system: H2(g)+I2(g)------>2HI(g)

luda_lava [24]

Answer:

The equation $\frac{[HI]^{2} }{[H_{2}[I_{2} ] }$ represent

(1) law of mass action

(2) mass action expression

(3) equilibrium constant expression

Explanation:

At a given temperature, the rate of a reaction at a particular instant is proportional to the product of the active masses of the reactants at that instant raised to powers which are numerically equal to the numbers of their respective molecules in the stoichiometric equation describe the reaction.

What is the wavelength of gamma ray electromagnetic radiation with a frequency of 2.73x10^20 Hz?

Amanda [17]

Answer:

1.10 × 10⁻¹² m

General Formulas and Concepts:

Chemistry - Atomic Structure

Speed of Light = Wavelength times Frequency

c = λν
c = 3.0 × 10⁸ m/s

Explanation:

Step 1: Define

ν = 2.73 × 10²⁰ Hz

Step 2: Find wavelength

3.0 × 10⁸ m/s = λ(2.73 × 10²⁰ Hz)

λ = 1.0989 × 10⁻¹² m

Step 3: Check

We are given 3 sig figs. Follow sig fig rules.

1.0989 × 10⁻¹² m ≈ 1.10 × 10⁻¹² m

For the reaction ag2s(s) ⇌ 2 ag+ (aq) + s2- (aq), keq = 2.4 × 10-4 and the equilibrium concentration of silver ion is [ag+] = 2.

Juliette [100K]

Answer : The concentration of silver ion is, $3.8\times 10^{-3}M$

Explanation :

Equilibrium constant : It is defined as the equilibrium constant. It is defined as the ratio of concentration of products to the concentration of reactants.

The equilibrium expression for the reaction is determined by multiplying the concentrations of products and divided by the concentrations of the reactants and each concentration is raised to the power that is equal to the coefficient in the balanced reaction.

As we know that the concentrations of pure solids and liquids are constant that is they do not change. Thus, they are not included in the equilibrium expression.

The given equilibrium reaction is,

$Ag_2S(s)\rightleftharpoons 2Ag^+(aq)+S^{2-}(aq)$

The expression of $K$ will be,

$K_{eq}=[Ag^+]^2[S^{2-}]$

$2.4\times 10^{-4}=(2.5\times 110^{-1})^2[S^{2-}]$

$[S^{2-}]=3.8\times 10^{-3}M$

Therefore, the concentration of silver ion is, $3.8\times 10^{-3}M$

Physical Properties: Physical properties can be observed or measured without changing the composition of matter. Physical properties are used to observe and describe matter. so physical changes are the change in temperature of the land and the evaporation of water and change humidity of the air. chemical change is the ripening of the orange
