How can genetic engineering be used to treat or cure diseases?

answer:

genetic engineering is the process in which a short segment of dna is manually added to an organism. the main aim is to achieve the desired function or trait that are missing or it is not found in an organism previously.

by using the genetic engineering technique we can insert the gene of interest into an organism or can delete the mutated gene or faulty gene in order to cure genetic disease. gene therapy is given to an individual who suffer from genetic disease and cancer.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
