Nanoscale building blocks and DNA 'glue' help shape 3D architectures

Scientists devised a new way of assembling ordered crystals made of nanoparticles. In this process, nanoparticles in the shape of cubes, octahedrons, and spheres coordinate with each other to build structures. The shapes are bound together by complementary DNA molecules on each type of particle.

During DNA replication, each strand of the original molecule acts as a template for the synthesis of a new, complementary DNA strand.

In Situ Hybridization (ISH) In Situ Hybridization (ISH) refers to localizing a specific DNA or RNA sequence in whole embryos or tissues/tissue sections/cells using a labeled probe. The probe is either a labeled complementary DNA (oligoprobe) or a complementary RNA (riboprobe).... http://www.creative-diagnostics.com/In-Situ-Hybridization-ISH.htm

Central Dogma of Molecular Biology -DNA makes RNA -RNA makes Proteins -Proteins help DNA (and sometimes RNA) to replicate itself -And some Proteins, like those from retrovirus HIV can turn RNA back into DNA (called complementary DNA or cDNA for short)
