Sequencing methods are continuously updated and have become automated
Scientists keep improving the technology used to read DNA sequences. Modern sequencing machines now do this work automatically, making the process much faster and cheaper than before.
Real World
The Human Genome Project cost approximately £2 billion over 13 years, yet by 2024 Illumina's NovaSeq machines could sequence a full human genome in under 24 hours for around £150.
Exam Focus
Compare early manual Sanger sequencing with modern automated next-generation methods in terms of speed, cost, and scale.
Evaluation Scaffold
A four-step framework for high-quality evaluation. Use this for 'assess', 'evaluate', and 'to what extent' questions.
