How can a gene determine whether a person has albinism (give a molecular explanation.)?

1 answer:

4 0

The <em>TYR </em>gene is responsible for the production of the enzyme tyrosinase which is crucial in the production of melanin which is primarily responsible for skin pigmentation and for pigmentation of other organs. In albinism, there is mutation of the <em>TYR </em>gene therefore there will be no transcription of DNA to mRNA and no translation of mRNA to the enzyme tyrosinase leading to its deficiency. The deficiency of tyrosinase will eventually lead to the absence of melanin and ultimately, the absence of pigmentation in an organism.

Describe the relationship between fatty acid chain length, saturation, and the melting point or fluidity of fatty acids.

Advocard [28]

Answer:

Because double bonds cause the hydrocarbon chain to bend. Therefore, the fatty acids cannot compact tightly together, reducing the van der Waals interaction between the fatty acids. The melting point of fatty acids is also affected by chain length. The longer the hydrocarbon chain is, the higher the melting point.

Answer:

Prokaryotic, and eukaryotic cells share basically four common features:

1) A plasma membrane which is known as outer covering membrane it helps to separate the interior part of the cell from its surrounding.

2) Cytoplasm which is consisted of gel like region inside the cell where other parts of the cell are found.

3) Genetic material of the cell which is known as DNA.

4) Ribosomes, which helps in protein synthesis.

Eukaryotic cells rely on the molecular energy of ATP to sustain all of the reactions necessary to maintain life, in the absence of ATP, these reactions would come to a halt, and the cell would inevitably die.

ATP is a molecular compound that provides the energy needed by most cells to survive. ATP represents Adenosine triphosphate, which is an organic compound that provides energy to drive the essential metabolic reactions of living cells, such as:

Muscle contractions
Nerve impulses
Chemical synthesis
Nutrient absorbtion

In the situation in which a cell was to run out of ATP, these reactions would stop, given that they require ATP to function. This means that the cell would not be able to send or receive nerve signals, absorb the nutrients it needs, or even create necessary compounds such as proteins. The stoppage of these functions would lead to the death of the cell.
