Answer:
The correct answer is D A gene is the entire DNA sequence that affects the production of a protein.
Explanation:
A gene cannot be the entire DNA sequence because an entire DNA sequence contain both coding part or exons and non coding parts or introns.
But according to the defination of the gene we know a gene is all the DNA molecules that encodes that primary gene product which may be either RNA or protein.
Gene sequence does not includes non coding parts or introns.
Well, if the Earth did not rotate, I believe life on Earth would cease to exist. Hope this helped!

Cell signalling pathways are used to maintain homeostasis. Enzymes are normally present in adequate concentrations but whenever the need for a particular enzyme or protein arises, cell signalling is used.
Signal is sent to that particular cell, the process of genetic expression is activated. A gene that codes for that particular protein(enzyme of interest) goes through transcription, where that genes DNA is copied to make a messenger RNAmolecule, which is further expressed by a process called Protein expression. Lastly, transported to that particular area where it is needed.
