Web6 feb. 2024 · What is a parent strand? Leading Strand and Lagging Strand The first one is called the leading strand. This is the parent strand of DNA which runs in the 3′ to 5′ direction toward the fork, and it’s replicated continuously by DNA polymerase because DNA polymerase builds a strand that runs antiparallel to it in the 5′ to 3′ direction. WebIn fact, until the 1950s, the structure of DNA remained a mystery. In this article, we'll briefly explore how the double-helical structure of DNA was discovered through the work of James Watson, Francis Crick, Rosalind Franklin, and other researchers. Then, we'll take a look at the properties of the double helix itself.
