What is the function of the bicoid gene?

Answer 1

Bicoid is a maternal effect gene whose protein concentration gradient patterns the anterior - posterior axis during Drosophila embryogenesis.

Bicoid protein gradient formation is one of the earliest steps in fruit fly embryo anterior - posterior patterning.

Bicoid is one of few proteins which binds both DNA and RNA . It regulates the transcription of RNA and the translation of DNA.

The bicoid gene is responsible for providing the anterior-posterior axis information during the development of Drosophila melanogaster (fruit fly) embryos. It helps in the formation of the head and thorax structures by regulating the expression of specific target genes.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
