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Generally, when there is no requirement of gene anymore, the acetyl groups from the histones get withdrawn by the activity of histone deacetylase enzyme (HDAC9) that makes the DNA tightly wrapped and inaccessible again.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.
Answer:
A
Explanation:
a bacteria takes a longer time to spread throughout the body
This isn’t multiply choice right? I believe it’s “they stay low to the ground”
Hope that helps
Answer:
Ok there is no figure 2.1 shown but I am going to guess that it is the epidermis as that is a plant tissue that is transparent
The reason it is transparent is because it is there to protect the inside of the plant that houses photosynthesizing plastids (chlorophyll) and by being transparent more light can get in and aid in the photosynthesis
