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:
Science and technology improve the our lives. This is thanks to the many discoveries science have gifted us. When it comes to science, scientists have discovered all type of drugs that helped us raise our life expectancy. Technology advances at the same time science does, as we discover new natural resources to use we make simple task faster and easier with technology, also makemas our health care system more acurate and efective
Answer:
There are two kinds of respiration: Aerobic and Anaerobic. ... Aerobic respiration takes place in the presence of oxygen, produces a large amount of energy. Carbon dioxide and water are produced as the waste products. Anaerobic respiration takes place without the use of oxygen, produces small amounts of energy.
