Individuals with these mutations typically have familial hypercholesterolemia.
These genes provide information for the formation of the low-density lipoprotein receptor, a receptor that binds to low-density lipoproteins (LDLs). LDLs carry the cholesterol in the blood and regulate the amount of cholesterol in the circulation. Mutations to these genes either reduce the number of receptors or cause several disruptions to their function. This results in high blood cholesterol levels and in a higher risk for heart disease.

<span>People who have defective genes for LDL receptors often have familial hypercholesterolemia. This is a genetic disorder that is caused in chromosome 19. It makes the body unable to remove lipoprotein that is low density, or LDL, which is type of protein that creates cholesterol in the blood. It will result in high amounts of LDL in the blood.</span>

Robert Hooke observed the thin slice of cork cells present in the plant cells. In 1665, Robert Hooke referred these empty tiny box-like cavities as cork cells.

<h3>What is Robert Hooke's Observation?</h3>

In 1665, Robert Hooke used a microscope to examine a tiny box-like empty cavities which are referred to as cork cells. He observed that the cork was made up of tiny units that looked like a honeycomb. He referred to them as cells, and he was the first to find a dead cell. This observation has a major contribution in the cell theory.

Hooke published his results under the title Micrographia, about his microscopic observations on several plant tissues. He is remembered as the coiner of the word “cell,” referring to the cavities he observed in thin slices of cork. The cork cells protect the tree from bacterial or fungal infection. It prevents water loss through the bark.
