Correct answer is option D.
Transcription activators accelerate transcription, while transcription factors assist RNA polymerase binding.
<h2><u>
</u></h2><h2><u>
Explanation</u></h2>
Transcription factors are the proteins which help in proper binding of RNA polymerases in the promoter region of DNA so as to facilitate transcription.
Activators on the other hand, help in the enhancement of the transcription rate.
Transcriptional activators are basically proteins which bind to the regulatory elements known as enhancers so as to increase the rate of transcription. Enhancers are specific DNA sequences, which may be present in the upstream or downstream region of the gene which is going to be transcribed.
It may be noted here that transcription factors are only present in eukaryotes. In prokaryotes, sigma factors are present instead of transcription factors to facilitate proper binding of RNA polymerases on the DNA.
Answer:
Hyperimmunoglobulinemia E Syndrome
Explanation:
Hyperimmunoglobulinemia E Syndrome or Job syndrome is an immunodeficiency disorder in which the white blood cells are incapable of producing an inflammatory response to infectious organisms. It is an autosomal dominant disorder. It is characterized by recurring bacterial infections, specially of lung and skin. There are also other symptoms like abromalities in vascular or skeletal system and elevated IgE level.
Symptoms like frequent formation of pus pockets in skin, lungs or joints usually begin during infancy. These pus pockets are formed due to infection by staphylococcal bacteria. Treatment usually consists of antibiotics to fight infection and anti histamines to relieve the symptoms like rash and itching. Sometimes drugs can also be administered to modify immune system.
Colonists made soap from an animal fat and potassium hydroxide. In interaction of fat and alkali there is a hydrolysis reaction. At the same time salts of a potassium and alcohols are formed.
Answer:It’s the independent variable
