Answer: (TFIID) TBP-> TFIIB IIA--> TFIIF RNA POL II
Explanation:
Remember that in eukaryotic organisms, transcription and processing are coupled processes. There are 3 different types of Rna pol. In the case of RNA pol II transcribes genes that encode proteins (mRNA synthesis). Transcription factors are involved, for example: TFIID, TBPs, TAF (recognizes TATA promoter center, regulatory functions), TFIIA (stabilizes TBP union, antirepressant function), TFIIB (RNA Pol II starting point selection).
Answer: 1. The resting membrane potential would become less negative (more positive).
Explanation:
Resting membrane potential is a voltage carried by a resting (non-signaling) neuron, or called as resting potential, across its membrane. The resting potential is determined by ion concentration gradients across the membrane, and the permeability of the membrane to each ion form.
In a resting brain, there are gradients of concentration across the Na+ and K+ membranes. Forces shift their gradients down through channels, resulting in a separation of charges that provides the potential for rest. The membrane is much more permeable to K+ than to Na+, so the resting potential is similar to K+'s potential for equilibrium.
Hence, the correct option is 1. The resting membrane potential would become less negative (more positive).
Answer:
A bacteriophage attaches itself to a susceptible bacterium and infects the host cell. Following infection, the bacteriophage hijacks the bacterium's cellular machinery to prevent it from producing bacterial components and instead forces the cell to produce viral components.
Explanation:
Answer: true : A pure substance is something that occurs in nature. An element is made up of one type of atom only and cannot be split further. A compound has the combined properties of the elements from which it is made. Atoms show the macro properties of an element.
