What is the function of the COI gene?
Abstract. The mitochondrial cytochrome oxidase subunit 1 (COI) gene is one of the most popular markers used for molecular systematics. Fragments of this gene are often used to infer phylogenies, particularly the region near the 5′-end, which is used by the DNA Barcoding Consortium.
Why is the COI gene used in DNA barcoding?
The DNA barcoding system using the cytochrome c oxidase subunit 1 mitochondrial gene (cox1 or COI) is highly efficient for discriminating vertebrate and invertebrate species. In the present study, we examined the suitability of cox1 as a marker for Trypanosoma cruzi identification from other closely related species.
Is COI a protein coding gene?
COI is a protein-coding gene, and as such, has an open reading frame.
Where is the COI gene located in the genome?
Structure. One of 37 mitochondrial genes, the MT-CO1 gene is located from nucleotide pairs 5904 to 7444 on the guanine-rich heavy (H) section of mtDNA.
What is COI in DNA barcoding?
The mitochondrial gene cytochrome c oxidase I (COI) is commonly used for DNA barcoding in animals. However, most of the COI barcode nucleotides are conserved and sequences longer than about 650 base pairs increase the computational burden for species identification.
What is a COI sequence?
Currently, COI gene sequences are used as a main molecular identification tool for insects (12-14). The subfamily Luciliinae is one of the major groups in the Family Calliphoridae (7). However, there have been limited studies about COI sequences of Korean Luciliinae fly species (15, 16).
What is the significance of using COI primers?
Biodiversity analyses show that richness is sensitive to primer choice and the combined use of multiple COI amplicons recovers higher richness. Thus, to recover maximum richness, multiple primer sets should be used with COI metabarcoding.
Is COI highly conserved?
COI, however, is one of the most conserved mitochondrial protein-coding genes in animals (Mueller, 2006), and thus displays a better phylogenetic signal (Hebert et al., 2003b).
What does COI mean biology?

Is COI a primer?
All degenerated COI primers showed superior detection rates (up to 100% of insects and 98% of all morphotaxa) and more consistent read abundances compared to the standard Folmer barcoding primers that lacked any base degeneracy (Folmer et al., 1994; Elbrecht and Leese, 2015).
What are COI sequences?
How long is COI gene?
about 650 base pairs
The commonly used DNA barcode of animal species is the mitochondrial gene cytochrome c oxidase I (COI) with a length of about 650 base pairs (bps).
What is COI sequence?
What is the COI gene used for?
The mitochondrial cytochrome oxidase subunit 1 (COI) gene is one of the most popular markers used for molecular systematics. Fragments of this gene are often used to infer phylogenies, particularly the region near the 5′-end, which is used by the DNA Barcoding Consortium.
Is cytochrome c oxidase subunit I (COI) gene useful for muscid identification?
Cytochrome c oxidase subunit I (COI) gene has been widely utilized. Nonetheless, to achieve correct identification of an unknown sample, it is important to survey certain muscid taxa from its geographic distribution range. Accordingly, the aim of this study is to contribute more geographically specific.
What is cloning and how does it work?
Cloning allows for the creation of multiple copies of genes, expression of genes, and study of specific genes. To get the DNA fragment into a bacterial cell in a form that will be copied or expressed, the fragment is first inserted into a plasmid.
Can COI gene help in the identification of muscid flies?
The Application of COI Gene for Species Identification of Forensically Important Muscid Flies (Diptera: Muscidae) Muscid Flies (Diptera: Muscidae) are of great forensic importance due to their wide distribution, ubiquitous and synanthropic nature.
