An illustration of an insertion at chromosome level

Genetic Insertion is the addition of one or more nucleotide base pairs into a genetic sequence. Nucleotides are Organic compounds that consist of three joined structures a nitrogenous base a Sugar, and a Phosphate group In Molecular biology, two Nucleotides on opposite complementary DNA or RNA strands that are connected via Hydrogen bonds are called This can often happen in microsatellite regions due to the DNA polymerase slipping. Microsatellites, or Simple Sequence Repeats (SSRs are polymorphic loci present in nuclear and organellar DNA that consist of repeating A DNA Polymerase is an Enzyme that assists in DNA replication.

On a chromosome level, an insertion refers to the insertion of a larger sequence into a chromosome. A chromosome is an organized structure of DNA and Protein that is found in cells. This can happen due to unequal crossover during meiosis. In Biology or life science meiosis (pronounced my-oh-sis is a process of reductional division in which the number of chromosomes per cell is cut in half

N region addition is the addition of non-coded nucleotides during recombination by terminal deoxynucleotidyl transferase. Genetic recombination is the process by which a strand of genetic material (usually DNA; but can also be RNA) is broken and then joined to a different DNA molecule Terminal Deoxynucleotidyl Transferase, also known as TdT and terminal transferase, is a specialized DNA polymerase expressed in immature pre-B pre-T

P nucleotide insertion is the insertion of palindromic sequences encoded by the ends of the recombining gene segments. A palindrome is a word phrase number or other sequence of units that can be read the same way in either direction (the adjustment of punctuation and spaces between words
