Answer:
This is through the process of methylation and phosphorylation of histones tails.
Explanation:
The addition of a methyl group to the amino acid of the histones of the nucleosomes that compacted DNA in the nucleus is called mehtylation, while the addtion of phodpahte is phosphorylation
Its effects on gene expression depends on the number of <u> methyl groups, and type of amino acid that methylated. During transcription. </u>
<u />
The DNA double strands are compacted and therefore hidden from transcription factors and enzymes of transcription by the hitones tails of the neuclosomes, Methylation weaken the binding bonds between the tails and DNA structure ; thereby aiding the uncoiling of DNA from the tails.(nucleosomes).This chemical reaction aided DNA strands exposure to transcription factors and enzymes, for initiation of transcription. This explains the dyanmic activity of methylation
Futhermore phophorylation also favours unwrapping of DNA, by imitating modifying enzymes e.g H3Y41E and H3T45E and convert it to→→ H3Y41phopspahte to aid DNA unwrapping and accessibility to transcription factors and RNA polymerase Enzymes,
Answer:

I assume that you would be evaluating the whole animal if it’s a a physical examination so B
Answer:
C. These antibiotics interfere with protein synthesis within eukaryotic mitochondria.
Explanation:
Eukaryotic mitochondria have 70s ribosomes and is made up of 50s and 30s subunits which has similarities to the ribosomes of bacterial cells. This likeness
at times causes antibiotics that ought to be toxic to bacterial ribosomes to cause some toxicity in eukaryotic cells instead.
