DNA replication in bacterium Escherichia coli begins at a site in the DNA called At the replication fork, the strand is synthesized continuously while the strand is synthesized discontinuously (in fragments). The new DNA strand, which is synthesized discontinuously, initially consists of short DNA pieces that are called A short RNA primer at the beginning of each of the DNA fragments is synthesized by an enzyme called and this RNA primer is later removed by the enzyme called using its activity.

Make the complementary strand for the following DNA template and label both strands as 5 to 3 or 3 to 5 (P = phosphate in the diagram). Draw an arrow showing the direction of synthesis of the new strand. How many hydrogen bonds are in this double strand of DNA? template: PAGGCTCGOH new strand:
Which of the following most correctly describes a process that occurs during DNA replication? Group of answer choices Replication of the lagging strand occurs in the 5' → 3' direction—the leading strand in the 3' → 5' direction. Replication is continuous on the lagging strand and discontinuous on the leading strand. Okazaki fragments are DNA fragments synthesized on the lagging strand. DNA polymerase adds dNTP monomers in the 3′–5′ direction. Replication is continuous on the lagging strand and discontinuous on the leading strand.

Two _____________ are created as replication continues in both ______________ from this point. The replication fork is where _______________ is actively taking place. As replication continues, a ____________ is created. These bubble continue to grow until two ___________ have been formed.
Which of the following statements about replication is false? The proofreading function of DNA polymerases involves 3’ 5’ exonuclease activity. Origins of replication are rich in G-C nucleotide pairs. A characteristic of aging cells is that telomeres become shorter. The lagging strand is synthesized in the opposite direction as the movement of the replication fork. DNA polymerase is more accurate that RNA polymerase.

DNA Pol I-mediated replication is a high-fidelity (i.e., no mistakes) process C. DNA Pol III-mediated replication gives rise to two daughter strands, one which is made of only the original templates, and one of which is only newly synthesized polymer. D. In DNA, all 4 classes of nitrogenous bases are more or less equally represented E. A pairs with T and C pairs with G
