DNA sequencing - Khan Academy
DNA sequencing involves three main steps: 1) using PCR to amplify DNA fragments, 2) introducing dideoxynucleotides that halt DNA strand elongation, and 3) employing a computer to analyze the fluorescent labels on the DNA fragments to determine the sequence.
Polymerase chain reaction (PCR) - Khan Academy
PCR (Polymerase Chain Reaction) is a vital technique in molecular biology, enabling researchers to amplify specific DNA fragments exponentially. Essential for cloning, forensics, and medical diagnostics, PCR involves three main steps: denaturation, annealing, and extension.
The Calvin cycle - Khan Academy
Explanation of the Calvin cycle in photosynthesis, including its stages and importance in converting carbon dioxide into glucose.
Molecular mechanism of DNA replication - Khan Academy
Some other proteins and enzymes, in addition the main ones above, are needed to keep DNA replication running smoothly. One is a protein called the sliding clamp, which holds DNA polymerase III molecules in place as they synthesize DNA.The sliding clamp is a ring-shaped protein and keeps the DNA polymerase of the lagging strand from floating off when it re-starts …
