Technically, a demurrer is not a motion; a party does not file a motion for demurrer nor move the court to demur. Rather, a demurrer is a particular type of pleading and demurring is the act where a party formally requests the court to dismiss a cause of action (claim) or the entire complaint.
DNA also includes sugars and phosphate groups that make the phosphate-deoxyribose backbone. If you think of the structure of DNA as a twisted ladder, the rungs of the ladder are made from the nitrogenous bases.These bases pair up to make each step of the ladder. They also only pair up in a specific way.NA also includes sugars and phosphate groups that make the phosphate-deoxyribose backbone. If you think of the structure of DNA as a twisted ladder, the rungs of the ladder are made from the nitrogenous bases.
DNA, RNA and the central dogma DNA and RNA are biopolymers constructed from nucleotides. A nucleotide is made up of a sugar molecule (called ribose), a phosphate group and nitrogen-containing base (Fig. 1).NA differs from RNA in having an hydrogen (H) group instead of an oxygen and hydrogen (OH) group on the 2 position of the sugar (which is where the 'deoxyribo' part of DNA's name comes from). In both DNA and RNA, sugar and phosphate form the structural backbone of the molecule.
