Researchers have previously tried sticking down one end of a DNA molecule to stretch it out, but found that the thermal fluctuations could still cause movement and blurring. "Stretching DNA refers ...

For the first time ever, scientists have captured a single DNA molecule replicating on video — and it’s changing the way we think about the entire process. One of the most surprising findings ...

A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes.

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding ...
