Use the template of a replication fork to draw arrows that represent both continuous and discontinuous DNA synthesis. Draw one long arrow to show continuous DNA synthesis and three arrows to show discontinuous DNA synthesis. The arrows should point in the direction of nucleotide addition, and the three arrows showing discontinuous synthesis should be numbered 1, 2, and 3, in the order of fragment synthesis.

Explanation:

Deoxyribonucleic acid (DNA) synthesis is the biological process by which DNA molecule is created. In the cell, each of the two strands of the DNA molecule acts as a template for the synthesis of a complementary strand. This strands are separated during replication (DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule). DNA polymerase synthesizes the new strands by adding nucleotides that complement each (template) strand.

Deoxyribonucleic acid (DNA) synthesis is continuous because extension of a single ribonucleic acid (RNA) primer occurs without interruption into the replication fork as it continues to open to the right as seen on the diagram below. On the upper lagging strand which is the discontinuous synthesis, here synthesis is discontinuous, since new RNA primers must be added as opening of the replication fork continues to expose new template.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
