Producing a contraction that changes both the length and the shape of the cell
It is a fish of Oder that compromises catfishes.
The neurotransmitter in the body
which prepares it for "fight or flight" reaction is EPINEPHRINE. The
level of Epinephrine is remarkably high in patients who have anxiety-related
disorders. Also known as adrenalin or adrenaline, epinephrine is a hormone and at the same time a neurotransmitter; it is also used as medication.
The correct answer is: b. It is free to bind to another promoter and begin transcription
Transcription is the first step of gene expression in which DNA molecule is copied (transcribed) into RNA (mRNA) by RNA polymerase. The process of transcription is divided into three phases:
1. Initiation
• RNA polymerase with transcriptional factors bind to gene promoter
• RNA polymerase unwinds DNA double helix (transcription bubble is formed)
2. Elongation
• RNA polymerases adds nucleotides complementary to DNA
3. Termination
• RNA polymerase gets to stop codon (transcribes a sequence of DNA known as a terminator)
• Formed complementary RNA strand is released from DNA-RNA complex.
RNA polymerase is also released and can transcribe some other gene by binding to its promotor. RNA polymerase will transcribe just the genes whose products are needed at a particular moment.
A decomposer is an organism usually a bacteria or fungus that decomposes organic material.
Decomposers are considerd the last tropic level because they feed on everything.
