Answer:
Yes.
Explanation:
Recent developments in biology have made it possible to acquire more and more precise information concerning our genetic makeup. Although we have only begun to see the most far-reaching effects of these developments and the completion of the Human Genome Project, scientists can even today identify a number of genetic disorders that may cause illness and disease in their carriers. The improved knowledge regarding the human genome will, it is predicted, soon make diagnoses more accurate, treatments more effective, and thereby considerably reduce and prevent unnecessary suffering. The knowledge can also be, however, depending on the case, futile, distressing, or plainly harmful. We propose to answer in this article the dual question: who should know about our genetic makeup and why? Through an analysis of prudential, moral, and legal grounds for acquiring the information, we conclude that, at least on the levels of law and social policy, practically nobody is either duty-bound to receive or entitled to have that knowledge.

The correct answers are:
- Methylation of histone tails in chromatin can promote condensation of the chromatin.
- DNA is not transcribed when chromatin is packaged tightly in a condensed form.
- Acetylation of histone tails is a reversible process.
- Some forms of chromatin modification can be passed on to future generations of cells.
- Acetylation of histone tails in chromatin allows access to DNA for transcription.
Histone modifications are post-translational modifications of histone protein that can affect gene expression by altering chromatin structure or recruiting histone modifiers.The most common modifications are methylation, phosphorylation, acetylation and ubiquitylation. All of them affect the binding affinity between histones and DNA and thus loosening (gene activation) or tightening (gene repression) the condensed DNA.
Histone methylation is a transfer of methyl group by histone methyltransferases to lysine or arginine amino acid of protein. Effect of methylation depends on the type of protein that is modified. Demethylation is the reverse process.
Histone acetylation is the process of adding of an acetyl group(by histone acetyltransferases) to histone proteins and it can also activate or inhibit the gene expression. Deacetilation is reverse process.
What are your options because i have a lot that apply
The correct answer is option A, that is, placer deposits.
The concentration of heavy deposits known as the placer deposits are produced by the gravitational action, generally found in streams. The minerals that take place as placer deposits comprise copper, gold, magnetite, cassiterite, and copper.
The formation of placer deposits takes place when the metal-bearing rock on land is weathered and the generated debris is washed down to the sea by the rivers. Further by the action of waves, currents, and rides the particles of heavy metal gets amassed to produce mineral sand deposits. These generally occur as beach deposits.
