Binary Fission: Binary fission, asexual reproduction by a separation of the body into two new bodies. In the process of binary fission, an organism duplicates its genetic material, or deoxyribonucleic acid (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA.
Budding: Budding, in biology, a form of asexual reproduction in which a new individual develops from some generative anatomical point of the parent organism. In some species buds may be produced from almost any point of the body, but in many cases budding is restricted to specialized areas. The initial protuberance of proliferating cytoplasm or cells, the bud, eventually develops into an organism duplicating the parent. The new individual may separate to exist independently, or the buds may remain attached, forming aggregates or colonies.
Spores: Spore, a reproductive cell capable of developing into a new individual without fusion with another reproductive cell. Spores thus differ from gametes, which are reproductive cells that must fuse in pairs in order to give rise to a new individual. Spores are agents of asexual reproduction, whereas gametes are agents of sexual reproduction.
Vegetative Propagation: Vegetative propagation is a form of asexual reproduction of a plant. Only one plant is involved and the offspring is the result of one parent. The new plant is genetically identical to the parent.
Asexual Reproduction: Asexual reproduction (i.e., reproduction not involving the union of gametes), however, occurs only in the invertebrates, in which it is common, occurring in animals as highly evolved as the sea squirts, which are closely related to the vertebrates. Involves the division of the body into two or more parts (fragmentation) and the regeneration of missing body parts

Answer:
Synthesis, DNA helicase, topoisomerase, leading strand, lagging strand, DNA polymerase, nucleotides, primase, lagging strand, nucleotide, DNA ligase
Explanation:
During the process of DNA replication, the whole molecule gets copied in the <u>synthesis or S</u> phase of the cell cycle. The DNA strands are separated by the enzyme <u>helicase</u> while <u>topoisomerase</u> keeps it from overwinding. The 2 strands are copied differently. The <u>leading</u> strand is made continuously, while the <u>lagging</u> strand is synthesized in small sequences called Okazaki fragments. The main enzyme involved in DNA replication is <u>DNA polymerase</u>. This enzyme can only add nucleotides to an existing strand, so short sequences of <u>nucleotides (primer)</u> made by the enzyme <u>primase</u> are needed for the process of elongation. In the <u>lagging</u> strand, the enzyme DNA polymerase one removes the short tj sequences and fills the gaps, while <u>DNA ligase</u> joins the fragments.
