Explain the nature of bond found in a DNA molecules

1.	Explain the nature of bond found in a DNA molecules
Answer» The\xa0DNA\xa0double helix has two types of\xa0bonds, covalent and hydrogen. Covalent\xa0bonds\xa0exist within each linear strand and strongly\xa0bond\xa0bases, sugars, and phosphate groups (both within each component and between components).\xa0The nucleotides in a strand of DNA are held together by phosphodiester bonds (a specific type of covalent bond). The two strands of DNA are held together by\xa0hydrogen\xa0bonds that form between the nitrogenous bases in one strand and the nitrogenous bases in the other strand.\xa0Covalent\xa0bonds\xa0occur within each linear strand and strongly\xa0bond\xa0the bases, sugars, and phosphate groups (both within each component and between components).\xa0Hydrogen bonds\xa0occur between the two strands and involve a base from one strand with a base from the second in complementary pairing.
