Answer:
VEGETATION 
Explanation:
It is referred to as an infected mass due to the production of bacteria in one heart valves. This infected mass can be due to bacteria in the bloodstream during any dental work, or any similar process related to bloodstream. This infected mass is called VEGETATION and related to endocarditis which is composed of fibrin and platelets.
 
        
                    
             
        
        
        
Both transcription and DNA replication are essential and significant genetic mechanisms. 
Transcription is a process where the genetic material i.e. DNA  is getting converted or transcribed to RNA by an enzyme RNA polymerase. 
Whereas the DNA replication is a process where, doubling or copying of DNA  from original DNA (identical replica copies). Which is the basis for biological inheritance. 
 
        
                    
             
        
        
        
A, B, and C. Luster is the light and how light reflects off of it, right?
So, in that case, a non metallic mineral, (think coal) wouldn’t shine much. A metallic mineral would shine, because it’s metal. And something that’s shiny obviously shines.
Go with A B and C.
        
             
        
        
        
Answer:
The positive charge of the histone proteins get reduced due to the process of histone acetylation, thus making the wrapping of DNA around the histones less tightened. The loose connected DNA afterward associates with the transcription factors for the articulation of the genes situated in that area.  
Generally, when there is no requirement of gene anymore, the acetyl groups from the histones get withdrawn by the activity of histone deacetylase enzyme (HDAC9) that makes the DNA tightly wrapped and inaccessible again. In case, when less expression of histone deacetylase enzyme occurs, the process of deacetylation fails to take place. This indicates that within an immune cell, at the time of infection, the inflammatory gene, which was made available does not get re-wrapped firmly around the histones.
