The structure of DNA was made by one pair of scientists

The contributions of many scientists led to the model of DNA structure

The DNA structure is unknown because we can see it with a microscope

DNA molecules have a square shape as determined by Sir Francis Bacon

We know from scientists exactly how DNA and RNA molecules first formed on earth.

RNA likely evolved before DNA

Many scientists have done experiments trying to determine where the first DNA and RNA molecules came from

Early Earth environments, hydrothermal vents, and meteorites could all be sources of the first DNA and RNA molecules

Cyanobacterium and aerobic bacterium infect host cells for replication.

Ancestral eukaryotes evolved before ancestral prokaryotes.

Complex eukaryotic cells developed from simple prokaryotic cells.

Viruses transform from ancestral prokaryotes to ancestral eukaryotes through infolding.
