Analysis of Hunchback mRNA expression tells us what about Hunchback gene expression? That the Hunchback gene is always on That the Hunchback gene is not expressed in the fruit fly That the Hunchback gene is turned on and off during development Nothing

Person A express a gene can regulate the expression of multiple language gene. What could be the probable protein/enzyme that the gene could code for? How could the enzyme regulate gene expression?

Please answer question 10

Draw a diagram to illustrate how a concentrationgradient of a transcription factor along the anterior–posterior axis of a Drosophila embryo can create a region in the middle inwhich transcription of a target gene takes place without beingtranscribed in either the anterior or posterior region

The figure below shows the distribution of proteins during embryo development in Drosophila. These proteins  are encoded by which types of genes? Which proteins regulate the expression of these genes?

Is this right?

Which of the following statements is FALSE? The Delta protein itself is a transcription regulator; it controls the development of neural cells in Drosophila. Not all receptors trigger complex signaling cascades that use multiple components to carry a message to the nucleus; some take a more direct route to control gene expression. Some receptors activate a fast track to the nucleus; one such receptor is the protein Notch, which is activated by the binding of the transmembrane signal protein Delta. In plants, the ethylene signaling pathway turns on genes by relieving inhibition.

At which stage of the Central Dogma does MOST of the regulation of gene expression occur? O Post-transcriptional processing of the pre-MRNA O Post-translational processing of the polypeptide chain Transcription of pre-mRN O Translation of protein
