DNA methylation is a process by which methyl groups are added to the DNA molecule. Methylation can change the activity of a DNA segment without changing the sequence. When located in a gene promoter, DNA methylation typically acts to repress gene transcription.
Answer:
Maltose is a disaccharide sugar made up of two units of glucose.
In cyclic structure, the glucose exists in two anomeric forms; alpha and beta.
These glucose units can either joined by α (1→4) glycosidic bond or by β (1→4) glycosidic bond.
Thus, the maltose exists in two anomeric form alpha and beta.
The statement 'obtaining embryonic stem cells for use in therapy requires the destruction of embryos' would be used in an argument against the use of human embryonic stem cells for therapy. It is a type of stem cell therapy.
<h3>What are embryonic stem cells?</h3>
The embryonic stem cells are cells obtained from embryos that have the property to divide and specialize into different tissues.
The embryonic stem cells can be differentiated in the laboratory for the development of specific cell lineages.
The therapy using embryonic stem cells involves the use of these types of cells and the destruction of an embryo.

A. Organic compounds - C₃N₂H₄ , C₆H₅F and C₁₂H₂₂O₁₁
Organic compounds are compounds which have Carbon except few compounds such as carbon dioxide, cyanide. Other than Carbon, other elements also present such as Hydrogen, Oxygen and Nitrogen. But Carbon is considered as the main element of organic compounds.
B. Inorganic substances - AIBr₃ , CrO₃ and <span>H</span>₂<span>O</span>₂
Inorganic substances are the compounds which do not own C-H bonds. Most inorganic compounds do not have carbon as their element except few. (Cyanides, carbon dioxide, carbon monoxide and so on are considered as inorganic although they have carbon).
DNA code is transffered to mRNA in the nucleus through a process called transcription.
Nucleus, the control center of the cell is the organelle which intiates, enables, and manages the various simplex. compound and complex cellular activities. It also stores the DNA of the cell which is then replicated and recopied over a hundredth and thousandth times over through cell division processes. In the nucleoplasm -nucleolus, the inner part of nucleus of a cell is where the DNA to mRNA and to protein; vice-versa happens.
