Two strand of dna

WebTrue or false? DNA repair mechanisms all depend on the existence of two copies of the genetic information, one in each of the homologous chromosomes. DNA primase makes DNA primers for the synthesis of Okazaki fragments in the DNA lagging strand. The repair of double-stranded breaks by nonhomologous end joining is accurate. WebDNA molecules have an antiparallel structure - that is, the two strands of the helix run in opposite directions of one another. Each strand has a 5' end and a 3' end. Solving the structure of DNA was one of the great scientific achievements of the century.

WebA restriction enzyme is a DNA-cutting enzyme that recognizes specific sites in DNA. Many restriction enzymes make staggered cuts at or near their recognition sites, producing ends with a single-stranded overhang. If two … WebDuring DNA replication, each of the two strands that make up the double helix serves as a template from which new strands are copied. The new strand will be complementary to the parental or “old” strand. Each new double strand consists of one parental strand and one new daughter strand.
