Answer:
specific DNA elements
Explanation:
Gene regulation is a mechanism that acts to promote or repress the expression of a gene. It controls the rate and manner of gene expression. Gene regulation involves a complex set of interaction between genes, RNA molecules and proteins (transcription factors). A basic tool employed during gene regulation is the binding of proteins called transcription factors to specific DNA.
Transcription factors are proteins that play an important role in regulating the transcription of genes by binding to specific regulatory nucleotide sequences(DNA). Transcription factors (proteins) help turn specific genes on or off by binding to close DNA elements.
Transcription factors operate by either making it easy or hard for RNA polymerase (an enzyme that synthesizes new RNA molecule by attaching itself to DNA) to bind to the promoter of a gene. Transcription factors that boost gene transcription are called ACTIVATORS while those that inhibit gene transcription are called REPRESSORS.
Answer:
Energy.
Explanation:
Energy can be considered as the factor which is responsible for matter changing and moving in an animal's body. This energy is used by animal for a variety of functions. Energy helps them to be cured from injury and growth. Motion also required energy.
At high latitudes, ocean water receives less sunlight. Thus, the surface waters in the Arctic and Antarctica are not warmed much; in fact they are very cold
so false
