Answer:
Regulatory sites e.g enhancers and silencers
Explanation:
Gene expression involves the synthesis of gene products usually proteins and RNA. However, a certain product might not be needed at all or in small quantity. Gene regulation mechanism is the process that makes this happen. Gene regulation is the mechanism that acts to induce or repress the expression of a gene.
Gene regulation involves controlling the rate and manner of gene expression which is achieved through a set of regulatory proteins called transcription factors. Transcription factors bind to specific regulatory nucleotide sequences and help to turn "on or off" specific genes in the DNA.
Transcription factors can either be ACTIVATORS or REPRESSORS depending on whether they boost or inhibit gene expression. The binding sites for these regulatory proteins called TRANSCRIPTION factors are the regulatory nucleotide sequences on the DNA called enhancers and silencers.
Answer:
A. The nervous system collects and responds to information about
the internal and external environment.
Explanation:
Answer:
Maybe this helps! Atoms come together to form molecules because of their electrons. Electrons can join (or bond) atoms together in two main ways. When two atoms share electrons between them, they are locked together (bonded) by that sharing. These are called covalent bonds.
In the Nitrogen cycle there are basically four steps and bacteria is involved in three steps of the N-cycle namely – Nitrogen fixation, Ammonification and De-Nitrification.
The Decomposers bacteria are involved in the ammonification process, where they convert organic waste, rich in nitrogen into simpler compounds usually ammonia which is further broken down into nitrite and nitrate. This process usually occurs in the absence of light and oxygen by anaerobic/facultative bacterias.
