Genetics

Since parents can pass on their own mutations to their descendants, when faced with a genetic disease it is important to perform a family study to determine whether other members of the family [...]

If genetic disease is caused by the mutation of a single gene, it is a “monogenic” disease. There may be additional mutations in other genes, but just one can cause a disease. Other diseases are [...]

These are disorders caused by genetic mutations. Mutation expression pattern: Certain diseases are caused by the presence of a single genetic mutation: in other words, just one of the two copies [...]

They can be caused intrinsically, during physiological DNA replication processes, or by external factors such as radiation. A child may receive mutations present in their mother and father’s DNA [...]

The sequence of nucleotides (A, T, G, C) that makes up a gene can have variations: One nucleotide may have been replaced by another (a G instead of an A, for example). A part of the sequence may [...]

Genes are parts of DNA that contain the information necessary for the production of the proteins that make us up and enable the human body to function. They are composed of sequences of four [...]

DNA is deoxyribonucleic acid. It is a molecule that is present in nearly all of our cells, responsible for containing all of an individual or living being’s genetic information. This information [...]
