Translation of the Sxl MRNA in XY Embryos Results In

Question

Translation of the Sxl mRNA in XY embryos results in
A) functional SXL protein.
B) a polypeptide without regulatory functions.
C) synthesis of functional transformer protein.
D) repression of the genes required for male development.
E) repression of the genes required for female development.

Accepted Answer

In XY embryos, the Sxl gene is located on the Y chromosome and is inactive. Therefore, translation of the Sxl mRNA in XY embryos would result in a polypeptide lacking regulatory functions, as there is no functional SXL protein encoded by the gene in XY embryos.
