Transcription begins with the opening and unwinding of a little portion of the DNA double helix to expose the nucleotides on each DNA strand.

The act of transcription involves transferring information from a strand of DNA to a fresh messenger RNA molecule (mRNA) . DNA safely and permanently stores genetic material in the cell nuclei as a reference or template.

The ideal gas law can be defined as the general equation to describe the state of a perfect gas. This equation represents the product of the volume and pressure is equal to the product of the gas constant, number of moles of gas, and absolute temperature.

The ideal gas equation for a gas can be represented as shown below:

PV = nRT

where n is the moles of gas, T is the temperature, P is the pressure,  V is the volume,  and R is the gas constant.

Given, the number of molecules of gas =  6.022 × 10²³

The number of moles of gas = 1mol

The temperature of gas, T = 25°C = 25 + 273.15 = 298.15 K,

The pressure of gas, P = 125 kPa = 1.233 atm

Gas constant, R= 0.082 atmL/K mol

Frameshift Mutation changes the Amino Acid sequence as it impact on the folding of the protein.

The sequence of a protein is determined by the DNA of the gene that encodes the protein. A change in the gene's DNA sequence may lead to a change in the amino acid sequence of the protein. Some mutations do not result in changes in the amino acid sequence of the encoded protein and can be described as silent mutations. Other mutations result in abnormal protein products. Mutations can introduce new alleles into a population of organisms and increase the population's genetic variation. Some mutations that change DNA bases do not have any effect on the sequence of amino acids in the protein. These mutations are called silent mutations and they do not affect the structure or function of the protein because there is no effect on the amino acid sequence.

The atmospheric partial pressure of oxygen  refers to the amount of oxygen in the atmosphere, which is mainly influenced by the amount of oxygen in the air. The alveolar partial pressure of oxygen (PₐO₂) refers to the amount of oxygen in the air that has diffused into the alveoli in the lungs and is the amount of oxygen available for respiration.

This difference between these two exists because oxygen molecules must travel through the airways and across the alveolar-capillary membrane before they can reach the alveoli in the lungs.

The airways contain airway resistance, which limits the amount of oxygen that can diffuse into the alveoli from the atmosphere. Additionally, there is a gradient of oxygen between the alveoli and the surrounding capillaries, which affects the amount of oxygen that can pass across the alveolar-capillary membrane.

As a result, the amount of oxygen in the alveoli is always lower than the amount of oxygen in the atmosphere. That is why both differ in their own ways.

Three sodium ions are exported and two potassium ions are imported for each ATP molecule used by the pump. A protein in the cell called the Na,K-ATPase pump controls Na+ and K+ gradients across the membrane. Cells are capable of producing electrical signals as gradients change. Keeping the axon prepared for the next signal is the responsibility of the sodium-potassium pump.

Molarity of the solution is defined as the amount of solute in moles divided by the volume of solution in liters.

               M = moles of solute/liters of solution.

we can calculate the molarity by dividing the number of moles of solute by the total volume of liters of solution.

let's assume 100g solution. the mass percentage of hydrochloric acid within the solution is 19.0%. and the density of the solution that is give is 1.095g/mole. substituting all these values we can calculate the molarity of the solution.

mass Hydrochloric acid,

100g solution x (19.00g / 100g solution) = 19.00g Hcl

moles of hydrochloric acid is ,

19.00g HCl x (1 mole Hcl / 36.45g HCl) = 0.52126

then the solution is,

100g solution x (1mL solution / 1.095g solution) x (1L / 1000mL) = 0.091324L
