Keep in mind that the complementary strand will read from left to right in the 3′′ to 5′′ direction. Therefore, the complementary strand starts with 3’ and ends with 5’. ...

... Q: Why does DNA have a very regular 3dimensional shape while RNA has a varied 3-D shape? A: RNA is single-stranded so areas with complementary bases form loops and bend the RNA. DNA is double stranded, and the regularity of its structure only allows one 3D structure, a double helix. ...

Helitron (biology)

A helitron is a transposon found in eukaryotes that is thought to replicate by a so-called ""rolling-circle"" mechanism. This category of transposons was discovered by Vladimir Kapitonov and Jerzy Jurka in 2001. The rolling-circle process begins with a break being made at the terminus of a single strand of the helitron DNA. Transposase then sits at this break and at another break where the helitron targets as a migration site. The strand is then displaced from its original location at the site of the break and attached to the target break, forming a circlular heteroduplex. This heteroduplex is then resolved into a flat piece of DNA via replication. During the rolling-circle process, DNA can be replicated beyond the initial helitron sequence, resulting in the flanking regions of DNA being ""captured"" by the helitron as it moves to a new location.
