WebComplementary DNA strands are separated or "unzipped" for the replication process. Weak hydrogen bonds between complementary strands are easily disrupted during DNA replication because they are not high-energy chemical bonds. Duplication of chromosomes occurs during S phase of the cell cycle. WebDNA consists of two antiparallel strands of nucleotide chains held together by hydrogen bonds The method of DNA replication, where each original strand is used as a template to build a new strand, is called the semiconservative method The enzyme that catalyzes the synthesis of new DNA molecules is called DNA polymerase.

WebA. the distance between the two phosphodiester backbones remains constant. B. the two strands are antiparallel. C. the distance between one base pair and the next remains constant. D. each base pair is held together by three hydrogen bonds. A. the distance between the two phosphodiester backbones remains constant. WebIn Watson and Crick's model, the two strands of the DNA double helix are held together by hydrogen bonds between nitrogenous bases on opposite strands. Each pair of bases lies flat, forming a "rung" on the ladder of the DNA molecule. Base pairs aren't made up of just any combination of bases. thermostat for quadrafire pellet stove

WebTwo strands of DNA are held together by phosphodiester bonds between bases on opposite strands B. DNA strands form a helical structure C. It contains one strand of DNA D. Bases on opposite strands are hydrogen bonded together E. The bases in the DNA molecule point outwards, away fro the central axis of the molecule. B. and D. WebThe two strands of DNA are held together by hydrogen bonds between the paired bases. As a result of its involvement in a chemical reaction, an enzyme is unchanged by the reactants or products. An enzyme is a macromolecule that acts as a catalyst, a chemical agent that speeds up a reaction without being consumed or changed by the earlier reaction.
