What happens when your DNA is damaged?

DNA damage is an abnormal chemical structure in DNA, while a mutation is a change in the sequence of standard base pairs. DNA damages cause changes in the structure of the genetic material and prevents the replication mechanism from functioning and performing properly.

What causes double stranded DNA?

The genome of a cell is continuously damaged, which is inevitable because DNA damage often arises as a result of normal cellular processes. The result is double-strand breaks (DSBs) in the chromosome. A DSB can also be caused by environmental exposure to irradiation, other chemical agents, or ultraviolet light (UV).

What is double stranded DNA test meant for?

The anti-double stranded DNA (anti-dsDNA) test is used to help diagnose lupus (systemic lupus erythematosus, SLE) in a person who has a positive result on a test for antinuclear antibody (ANA) and has clinical signs and symptoms that suggest lupus.

How are DNA breaks repair in prokaryotes?

In bacteria such as Escherichia coli, homologous recombination is the predominant pathway for repairing DNA breaks. Moreover, there are two overlapping, but distinct, homologous recombination pathways through which this occurs.

What is direct reversal repair?

Direct reversal repair is a mechanism of repair where the damaged area or lesion is repaired directly by specialised proteins in our body. It is the simplest form of DNA repair and also, the most energy efficient method. It does not require a reference template unlike the other single-strand repair mechanism.

What is direct reversal of DNA damage?

Direct reversal of DNA damage is one repair mechanism used to restore damaged DNA. Although this is the most energy efficient method, few types of damaged DNA are repaired in this way.

What is direct repair?

In the automotive repair industry, a Direct Repair Program, also known as a DRP is a relationship that is formed between an insurance company and an auto body shop. When an insurance agent is working with someone whose vehicle has been damaged, they will give suggestions of auto body shops to their clients.
