Definition Of Bicoid Gene

The definition of bicoid in dictionary is as.

Definition of bicoid gene. In order for development to continue hunchback is needed in an area that is declining in amount from anterior to posterior. Grammatically this word bicoid is a noun more specifically a countable. What does bicoid mean as a name of something. It is also involved in the activation of kruppel expression.

This definition of the word bicoid is from the wiktionary dictionary where you can also find the etimology other senses synonyms antonyms and examples. For example bicoid acts as a transcriptional activator of hunchback gene transcription. Bicoid bcd functions as a morphogen during drosophila development. Accordingly bcd mrna is maternally localized to the anterior pole of the embryo and bcd forms an anterior posterior gradient which functions in a concentration dependent fashion.

Noun genetics a gene in drosophila and related flies that specifies which end of an egg will be the anterior and become the fly s head by setting up a concentration gradient of the bicoid protein printed dictionaries and other books with definitions for bicoid. Bicoid is a maternal effect gene whose protein concentration gradient patterns the anterior posterior a p axis during drosophila embryogenesis bicoid was the first protein demonstrated to act as a morphogen. Definition noun 1 a kind of maternal effect gene as in bicoid gene whose function is to code for products used for establishing the normal patterning of anterior parts head and thorax of the embryo. Gene expression in these nuclei is regulated by the bicoid hunchback and caudal proteins.

Thus nuclei receiving identical amounts of bcd should express the same target genes. 2 the gene product of bicoid attaching to microtubules and concentrating at the anterior ends of the embryo. Bicoid noun a gene in drosophila and related flies that specifies which end of an egg will be the anterior and become the fly s head by setting up a concentration gradient of the bicoid protein. Bicoid a maternal effect gene which is important for patterning of anterior parts head and thorax of drosophila embryos.

Although bicoid is important for the development of drosophila and other higher dipterans it is absent from most other insects where its role is accomplished by other genes. A gene in drosophila and related flies that specifies which end of an egg will be the anterior and become the fly s head by setting up a concentration gradient of the bicoid protein.
