Question

please answer and explain

Sex-lethal - 2 Stop Stop Transformer 1 Stop -11,2 | 3. - Stop What is the name of the process that is diagrammed above? As shown in the picture, the sxl protein causes A5. (5 points). The APOBEC enzyme deaminates cytosine to form uracil in both RNA and DNA. This is part of a natural anti-virus system that our cells use to protect themselves (or, try to). How might the deamination of cytosines help to deactivate present and future copies of virus nucleic acids?

this is all of the information that is provided for the question

Answer 1

This is a part of sex determination process in Drosophila where sxl gene controls three main processes:-

the development of female somatic fate;

the dosage compensation in males during embryonic development,

and finally, the sex specific development of female and male germ lines.

Sex lethal is an enzyme which paticipates in RNA splicing. It is not transcribed in males.

Its immediate target is transformer mRNA in females. It acts positively in splicing of transformer mRNA which in turn acts on downstream mRNA in sex specific splicing and thus transformer protein determines female fate.

First diagram is showing that sxl itself positively regulates its own mRNA splicing and in second it regulates the sex specific splicing of transfomer gene
