<span>Carbon is the answer you are looking for. However, not all carbon containing molecules are organic. Examples being carbon oxides such as CO (carbon monoxide) and CO2 (carbon dioxide). Some Chemists classify organic compounds as having a C-H bond present but this is not completely correct as this excludes molecules like benzenehexol (benzene with an alcohol group on each carbon rather than a hydrogen) which are considered organic. A solid definition of an organic molecule is not certainly agreed. Just remember that: all organic molecules contain carbon but not all carbon containing molecules are organic.</span>
Answer: The main bonding in DNA which renders the double helix structure so stable is that of hydrogen bonds. ... As well as this there are hydrogen bonds between the bases and surrounding water molecules, and this combined with the even stronger phosphodiester bonds in the sugar phosphate backbone make DNA very stable.
Explanation:
FDA issued a black box warning about the use of Tacrolimus and the development of cancer in animals and humans.
Tacrolimus is a topical drug used for dematitis. It is a chronic condition which the skin becomes inflammed, red, itchy. The inflammation is caused by the activation of immune function of the patient. Tacrolimus is used as topical agent to suppress the function of immune system and inflammation by inhibition of calcineurin. This is an enzyme needed for T cell production. T cells plays a big factor in the activation of immune system.
