Answer:
The chromatin structure undergoes various modification for proper gene expression. Histone acetylation, histone deacetylation, methylation and sumoylation are important for the epigenetics.
Epigenetics may be defined as the change in the genome that affect gene activity, its expression and heritable phenotypic change of the organisms. The DNA sequence is not altered in the epigenetic modification but the gene expression has been modified by methylation or acetylation.
I think it’s the cell wall
B) Animals are regularly fed and bathed
The DNA, RNA or the RNA Polymerase of the infected cell would not be virus's primary source of heritable information because it has the ability to integrate into host cell and get itself replicated, also it causes infection so multiplication becomes necessary.
Explanation:
The virus has reverse transcriptase enzyme in them which works slightly different. It transcribes RNA into DNA and eventually gets integrated into the genome of the host. It is here the DNA in the host cell is transcribed and translated. Thus it is modelled to have RNA as genetic material.
When virus infects the living cell by a process called a lytic infection, it injects its genetic material into it to get replicated and increase its number and eventually bursts the infected cell. Since a virus causes infection, it has to increase in number so it uses its own genome to get replicated.
Answer:
