Answer:
False
Explanation:
In eukaryotes apart from RNA polymerase, the transcription of genes requires many different proteins called transcription factors. These transcription factors are important to initiate and regulate transcription.
There are two types of transcription factors regulatory and basal transcription factors. Basal transcription factors regulate transcription by binding to a gene promoter and regulatory transcription factor regulates transcription by binding to some regulatory sequences for example enhancers and silencers.
Therefore only basal transcription factor binds to the promoter for regulating transcription. Therefore the statement is false.
The correct answer is letter B. the closer the star, the larger the Parallax angle. This is an illusion that is made through visual perspectives of observers of stars. A parallax can also be used to find the distance to the stars that are relatively close.
The answer is B. A tendon joins bone to muscle and a tendon joins bone to bone.<span />
Answer: Option C.
GAL80 would be able to bind to GAL4, and transcription of the genes involved in galactose metabolism would be repressed.
Explanation:
Gal 3, Gal 80 and Gal 4 are form of proteins which participate in metabolism. They constitute a galactose-responsive switch for the GAL genes When galactose is absent, Gal 80 bind to Gal 4, masking the Gal4AD prevent gene transcription and prevents Gal4-mediated promoter activation
Answer:
2
Explanation:
DNA is tightly packed up to fit in the nucleus of every cell. As shown in the animation, a DNA molecule wraps around histone proteins to form tight loops called nucleosomes. These nucleosomes coil and stack together to form fibers called chromatin
