DNA Sequencing topics include: Chain termination sequencing principles and automated sequencing. DNA sequencing is a laboratory technique that determines the sequence of nucleotides in a DNA molecule. The sequence of bases, often referred to by their chemical names A, T, C, and G, encodes the biological information that cells use to develop and operate. DNA sequencing involves the following steps: Nucleic acid extraction and isolation Library preparation Clonal amplification and sequencing Data analysis using bioinformatics Some DNA sequencing techniques include: Sanger...

DNA sequencing is a laboratory technique that determines the sequence of nucleotides in a DNA molecule. The sequence of bases, often referred to by their chemical names A, T, C, and G, encodes the biological information that cells use to develop and operate. DNA sequencing involves the following steps: Nucleic acid extraction and isolation Library preparation Clonal amplification and sequencing Data analysis using bioinformatics Some DNA sequencing techniques include: Sanger sequencing: Also known as the chain termination method, this technique is based on the selective incorporation of chain-terminating dideoxynucleotides (ddNTPs) by DNA polymerase during in vitro DNA replication. It is a fast, cost effective way of reading the sequence of small targeted regions of the genome. Maxam-Gilbert sequencing: This is a chemical-degradation method that allows for sequencing dsDNA without previous in vivo cloning steps. It relies on the specific modifications of the DNA nitrogenous bases (A, C, G & T) and subsequent cleavage of the ssDNA phosphate backbone at such specifically-modified sites. Shotgun sequencing: This technique involves randomly breaking up the genome into small DNA fragments that are sequenced individually. Computers then assemble the fragments by finding overlapping ends. Show less
