TAND-1 and TAND-2 of TAF-1 blocks the DNA binding cleft of TPB and the n-terminal stirrup.
<h3>Explain function of TAF(I).</h3>
- Part of a protein known as transcription factor IID can be made using instructions from the TAF1 gene (TFIID).
- The body's cells and tissues all have this protein, which connects to and binds to DNA there.
- The majority of genes' activity is controlled by transcription factor IID.
- A preinitiation complex made up of a number of initiation components must be assembled before RNA polymerase II can begin transcription of a gene from its core promoter region.
- It is believed that the TFIID transcription factor complex, which is made up of the TATA-binding protein (TBP) and TBP-associated factors (TAF(II)s), binds to the various promoters in a sequence-specific manner to initiate the assembly of this complex.
- Here, we identify and characterize a novel multiprotein complex made up of a number of TAF(II)s and other proteins but lacking either TBP or a TBP-like factor.
- In in vitro transcription experiments, this complex can take the place of TFIID on both TATA-containing and TATA-lacking promoters.

Answer:
A
Explanation:
Homeostasis is the maintaining of internal conditions. Answer A is correct because it is maintaining internal conditions which is the blood temperature.
Answer:
A problem that confounds attempts to organize the entire living world for study is the need of evolutionists to bring the entire diversity of living things ultimately into.
In biology, living things can all be classified in accordance with other living things that share a specified set of common characteristics. A major challenge to the process of classification is that, in evolution, that this involves the need to classify all living things. The challenges being that there are many species on planet earth that once existed and are now extinct (i.e. they cannot currently be studied in living form) and that there may be species that do exist that have yet to be discovered and therefore cannot be classified. Finally, due to the sheer number of species on earth, it will literally take hundreds of years for scientists to classify all species.
Answer: "B" epididmysis
Explanation: The epididmysis are coiled tubes that are right behind the testicles. These coiled tubes lie above the testicles. The epididmysis stores and collects sperm prior to ejaculation.
Answer:
Its a semipermaeble mambrane
Explanation:
Semipermeable membrane is a type of biological or synthetic, polymeric membrane that will allow certain molecules or ions to pass through it by diffusion.
