In Drosophila, tissues along the dorso-ventral axis of the embryo turn on different embryonic genes in response to a nuclear concentration gradient of the maternally derived Dorsal transcription factor. A. Explain in a few sentences how the concentration of Dorsal protein in the nuclei of the fly embryo becomes graded from high-to-low as one moves from the ventral to the dorsal side of the embryo.

regulation of gene expression. gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. these regulatory proteins bind to dna and send signals that indirectly control the rate of gene expression

explanation:

the statement is true

the correct answer is:

a population changes in response to a change in the environment.

emerging idea only occurs as a raw idea that could appear out of nowhere. meanwhile, to reach scientific consensus , that idea must be structured and tested over and over again through various experiments. the scientific consensus transforms the raw idea into idea that is more reliable through the process of scientific elimination.
