Explain how a single gene effects two or more independent pathways (Ex: White eye phenotype for a friut fly). Propose five hypothesis (details needed).

Solution

Answer :

Different genes controls different activities of the cell and also there are genes which controls more than one activity of the cell.

1) transcription factors controls the transcription process DNA to RNA formation and also controls the cell division S stage of cell cycle.

2 the hypothesis by Beadle and Tatum stated one gene one enzyme hypothesis which states each gene controls the synthesis if one enzyme. E. G eye color of fruit fly is control by one gene.

3( gene regukation: the gene responsible for color of the eye also controls the position if the eye.

4) by random mutagenesis and transferable p element present in Drosophila controls the mutation in the fly.

5) adaptation if the fruit flies also controls by transcription factors which intrun controls translation and protein synthesis and enzymatic activities. So we can see GAT one genes and it\'s activities are interrelated and sometimes independent and controlling the cellular activities and providing the best protection to the body.
