Missense mutations replace a base by another one, leading the codon to codify for another amino acid, aletirng the protein's function. This mutation leads to the production of a dysfunctional protein, because a Cysteine amino acid has been replaced by a Phenylalanine amino acid.

When a change occurs in a codon affecting a single base pair, it is known as a point mutation.

Points mutations might be either silent, missense, or nonsense.

A missense mutation is the point mutation that changes a DNA base by another one, and causes the mRNA codon to code for a different amino acid.

The mutation that replaces a single base for another one might have different consequences concerning the substitution site and changes in the physical structure of the protein.

For instance, if the substitution occurs near the protein active site, the polypeptide function might be severely affected.

In the exposed example, a cytosine nucleotide (C) has bee replaced by an adenine nucleotide (A).

This mutation leads to the production of a dysfunctional protein, because a Cysteine amino acid has been replaced by a Phenylalanine amino acid.

a ciliate. Ciliates are a type of single-celled organism belonging to the Ciliophora.

They are characterized by the presence of numerous hair-like structures called cilia, which are used for locomotion and feeding. Cilia are short, hair-like projections that cover the entire outer surface of the cell membrane.

These cilia beat in a coordinated fashion, creating a wave-like motion that allows the ciliate to move through the water.

Ciliates exhibit a wide range of shapes and sizes, but they are typically oval or elongated in form.

They have a well-defined nucleus and often possess other specialized structures such as contractile vacuoles for osmoregulation and oral grooves for feeding.

Ciliates are also known for their ability to undergo complex cell division processes, including conjugation, which involves the exchange of genetic material between two individuals.

Observing a single-celled organism with moving cilia under the microscope is a common sight in freshwater environments such as ponds, lakes, and streams, where ciliates are abundant.

Answer: The total mass in micrograms of the cofactor in a yeast colony containing 105 cells = 4357.5.

Explanation: Cofactor mass= cofactor per cell * cell count= 41.5pg/cell * 105 cells= 4357.5pg= 4.36 x ... The total mass in micrograms of the cofactor in a yeast colony containing 105 cells = 4357.5.

The total mass of cofactor A in the yeast colony is 3480 μg.

To find the total mass of cofactor A in a yeast colony containing 10^5 cells, we need to multiply the mass of cofactor A in an average yeast cell (34.8 pg) by the number of cells in the colony (10^5). First, convert the mass of cofactor A from picograms (pg) to micrograms (μg). 1 pg = 0.001 μg, so 34.8 pg = 0.0348 μg. Then, multiply 0.0348 μg by 10^5 to get the total mass of cofactor A in the yeast colony: 0.0348 μg * 10^5 = 3480 μg.

During the rising (depolarizing) phase of an action potential, ions of the element sodium (Na⁺) enter the neuron through channels.

The rising phase of an action potential refers to the initial depolarization of the neuron's membrane, where the electrical potential inside the neuron becomes more positive. This depolarization is primarily caused by the influx of positively charged ions, specifically sodium ions (Na⁺).

At rest, the neuron's membrane maintains a negative charge inside relative to the outside. When a stimulus triggers an action potential, voltage-gated sodium channels in the neuron's membrane open, allowing sodium ions to rapidly flow into the neuron. This influx of positively charged sodium ions causes the membrane potential to shift from negative to positive, leading to depolarization.

The influx of sodium ions is responsible for the rising phase of the action potential, as it brings the membrane potential closer to the threshold for generating an action potential. This depolarizing phase is crucial for the propagation of the electrical signal along the neuron.

Once the rising phase reaches its peak and the membrane potential surpasses a certain threshold, voltage-gated potassium channels open, allowing potassium ions (K⁺) to exit the neuron. This initiates the falling (repolarizing) phase of the action potential.

In summary, during the rising (depolarizing) phase of an action potential, sodium ions (Na⁺) enter the neuron through channels, leading to the depolarization of the neuron's membrane.
