Insertion (genetics)



 
 
Genetic Insertion is the addition of one or more nucleotide
Nucleotide

Nucleotides are molecules that comprise the structural units of RNA and DNA. Additionally, nucleotides play central roles in metabolism. In that capacity, they serve as sources of chemical energy , participate in cell signaling , and are incorporated into important cofactors of enzymatic reactions ....

Base pair

In molecular biology, two nucleotides on opposite complementarity DNA or RNA strands that are connected via hydrogen bonds are called a base pair ....

Microsatellite

Microsatellites, or Simple Sequence Repeats , are Polymorphism loci present in nuclear DNA and organellar DNA DNA that consist of repeating units of 1-6 base pairs in length....

DNA polymerase

A DNA polymerase is an enzyme that catalyze the polymerization of deoxyribonucleotides into a DNA strand. DNA polymerases are best-known for their role in DNA replication, in which the polymerase "reads" an intact DNA strand as a template and uses it to synthesize the new strand....

 level, an insertion refers to the insertion of a larger sequence into a chromosome. This can happen due to unequal crossover
Chromosomal crossover

Chromosomal crossover is the process by which two chromosomes pair up and exchange sections of their DNA. This often occurs during prophase 1 of meiosis in a process called synapsis....
 during meiosis
Meiosis

In biology or life science, meiosis is a process of reductional division in which the number of chromosomes per cell is halved. In animals, meiosis always results in the formation of gametes, while in other organisms it can give rise to spores....

N region addition is the addition of non-coded nucleotides during recombination
Genetic recombination

Genetic recombination is the process by which a strand of genetic material is broken and then joined to a different DNA molecule. In eukaryotes recombination commonly occurs during meiosis as chromosomal crossover between paired chromosomes....

Terminal Deoxynucleotidyl Transferase

Terminal Deoxynucleotidyl Transferase, also known as TdT and terminal transferase, is a specialized DNA polymerase expressed in immature, pre-B, pre-T lymphoid cells, and acute lymphoblastic leukemia/lymphoma cells....
