Question

How does sequence annotation contribute to the Human Genome Project's goals?

Options

• It physically separates DNA molecules into components

• It identifies genes and assigns possible functions to DNA sequences

• It removes non-coding sequences from the genome

• It combines all genes into a single chromosome

Answer 1

Sequence annotation, the sixth step in the HGP methodology, involves identifying genes within the sequenced DNA and assigning possible functions to these sequences. This process was crucial for transforming raw sequence data into meaningful biological information, enabling researchers to understand which regions of the genome encode proteins, regulate gene expression, or have other functional roles.
