Sex-linked gene

Definition

noun, plural: sex-linked genes

A gene located in the sex chromosome.


Supplement

In humans, the sex chromosomes are the X chromosome and Y chromosome. Hence, a sex-linked gene may occur in either of these sex chromosomes. Since the X chromosome is a rather large structure than the Y chromosome, the X chromosome carries more genes, which may not be found in Y chromosome. Thus, there are more sex-linked genes found in the X than in Y chromosome.

Examples of sex-linked genes are those genes that code for X-linked traits such as red-green colour blindness and haemophilia.

SUMO and gene expression

According to my understanding, I think inappropriate SUMO modifications in tumors is related to the uncontrolled gene expression in most cancers. I have learned this from http://www.protein-expression.net/archives/51 this site. Didn't know if this can help you, but good luck!

amplification in no RT control

I am doing some qRT PCR to assess changes in bacterial gene expression following exposure to antimicrobials. RNA has been isolated by trizol method and subsequently 'cleaned' on column and finally been DNase treated prior to reverse transcription. I ...

gene knockout mice

Unfortunately astrocytes are not different in the different areas of the brain, so an inactivation of a gene only in striatal astrocytes with a pure genetic approach is not possible. You might combine genetics with viral infection. You might produce an AAV containing the Cre ...
