This video shows replication of individual pieces of double stranded DNA. This is the first time DNA replication -- arguably, the fundamental process of life on Earth -- has been observed directly.
From the first unzip of the double helix to the final joining of DNA fragments, replication is a carefully coordinated process. Understanding it helps explain how life preserves its genetic code with ...
The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...
