What happens if a gene is defective?
When a gene mutation occurs, the nucleotides are in the wrong order which means the coded instructions are wrong and faulty proteins are made or control switches are changed. The body can’t function as it should. Mutations can be inherited from one or both parents. They are present in the egg and/ or sperm cells.

What happens if the wrong genes are turned on for a given cell type?
Like using the wrong tool for the job, if the wrong genes are turned on in a cell, it can cause a real mess. Worse, in some cases it can cause serious disease like cancer. Scientists have known this for decades.
How can you tell if a gene is turned on?
A protein, called the transcription factor, can either cover up the gene directions or reveal them, thus determining whether the gene is on or off. Recent discoveries have unveiled another means of gene regulation.
Can genes be damaged?
Genetic damage (genotoxicity) includes various aspects of DNA damage ranging from oxidative DNA base lesions and point mutations to chromosomal alterations.
Can DNA repair itself?
Most damage to DNA is repaired by removal of the damaged bases followed by resynthesis of the excised region. Some lesions in DNA, however, can be repaired by direct reversal of the damage, which may be a more efficient way of dealing with specific types of DNA damage that occur frequently.
Can fasting change your DNA?
These findings suggest that dawn to sunset 30-day intermittent fasting induces the repair of DNA damaged by ultraviolet and ionizing radiation.
What vitamins help cell regeneration?
However, studies on natural antioxidants such as vitamins (C, D, and E) and polyphenols on the regeneration potential of vascular cells is still in its infancy. The antioxidants can be endogenous or acquired exogenously as a part of a diet or dietary supplements.
Can cell damage be reversed?
Cell damage can be reversible or irreversible. Depending on the extent of injury, the cellular response may be adaptive and where possible, homeostasis is restored. Cell death occurs when the severity of the injury exceeds the cell’s ability to repair itself.
Can you repair your body?
The body’s ability to heal itself naturally is actually not a new thing. A fractured bone will regrow and heal the break. Cut yourself shaving, and the skin will heal. There are many examples of our body’s innate ability to heal injuries.
Which organs can repair themselves?
There are some human organs and tissues that regenerate rather than simply scar, as a result of injury. These include the liver, fingertips, and endometrium.
Can damage organs repair themselves?
Regeneration means the regrowth of a damaged or missing organ part from the remaining tissue. As adults, humans can regenerate some organs, such as the liver. If part of the liver is lost by disease or injury, the liver grows back to its original size, though not its original shape.
