Gene expression in developing organisms is regulated on several different levels. In many developing animals, regulation of gene expression is influenced by the action of Hox genes. Which of the following regulatory elements is produced by many Hox genes? a) signals from maternal cytoplasm, such as bicoid mRNA b) processing factors c) cell-surface molecules for cell—cell interactions d) transcriptional factors

d) transcriptional factors

Explanation:

Gene expression in developing organisms is regulated on several different levels. In many developing animals, regulation of gene expression is influenced by the action of Hox genes. Transcriptional factors regulatory elements is produced by many Hox genes.

Transcription factors are proteins that help turn specific genes "on" or "off" by binding to nearby DNA and Hox genes help lay out the basic body forms of many animals, including humans, flies, and worms. They set up the head-to-tail organization.

the framers of the constitution insisted that federal judges be nominated instead of elected due to their desire to have judges above the shifting whims of the masses.

the hope, whether achieved or not, was that federal judges would only be beholden to the law and that by not having judges be elected, they would be protected if that law dictated an outcome that ran counter to popular opinion.

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.
