Answer:
The correct answer is: Actinobacteria
Explanation:
Actinobacteria is a phylum of the Gram-positive aquatic or terrestrial bacteria that have high concentrations of guanine and cytosine in their DNA.
These bacteria are economically important to the human beings as they produce bioactive metabolites used in producing medicines and are also responsible for the <u>decomposition of organic matter of dead organisms in the soil.</u>
<u>Therefore, Actinobacteria will be the best bacteria to be used in the laboratory.</u>
Answer:
В, С, А
Explanation:
The process of clotting is known as the hemostasis which takes place in three steps: the vascular spasm, the formation of a plug of platelets and the coagulation.
In the given question, step B shows the process of vascular spasm in which the vascular blood vessels becomes constricted due to injury. After this, the platelets present in the blood starts accumulating at the site of injury. These platelets stick together and form a plug-like structure at the site of injury.
Later, step A takes place that is fibrin protein present in the blood starts forming a mesh-like structure which does not allow the bleeding and this process is known as coagulation.
Thus, the selected option is the correct answer.
It is true that all GAL structural genes have UAS elements in their enhancer regions.
UAS elements can be found in the enhancer regions of every GAL structural gene. An enhancer is a short portion of DNA (50–1500 bp) that can be bound by proteins (activators) to increase the likelihood of a particular gene being transcribed.
The GAL4-UAS system is a biochemical technique used to investigate gene expression and function in fruit flies. Two parts make up the system: the Gal4 protein, which is an activator of transcription in yeast, and the UAS (Upstream Activation Sequence), which is an enhancer to which GAL4 binds specifically to initiate transcription.
