Marker gene

Definition

noun, plural: marker genes

(genetics) A gene with known physical location, easily detectable phenotype, and whose pattern of inheritance can be followed.


Supplement

These markers are used to trace or identify specific region of a gene (especially one that is associated with an inherited disease) on a particular chromosome. These markers can be an enzymatic reporter gene, a selectable marker conferring antibiotic resistance or a cell membrane protein with a characteristic epitope.


Also called: genetic marker, DNA marker.

Re: How

multiple gene insertion by conventional transformation is very time consuming and required selectable marker genes :( . So I have to do different..................? Do you have any idea ????? :(

Orientation of genes

"to be cloned" part is not needed. Sorry When making a gene construct (before inserting into an expression vector), do we have to place the desired gene, the reporter gene and the marker gene in any specific direction or orientation? I have seen in most cases the ...

Reporter gene without fusion

I know that a reporter gene can be used to detect the foreign gene expression if it is fused with the foreign ... gene under a different promoter? If not, what is the use of placing a selectable marker and a reporter gene under the same construct (without a fusion) ? Thank you Regards
