Why is genome database and annotation relevant to Genome sequencing?   Are there any examples?

For each of the following scenarios describing gene annotation, choose the answer that best fits A researcher searches a database of sequence motifs for matches to parts of a gene's sequence. A researcher searches for a genomic region that includes particular characteristics that include the following: a CpG island near a promoter, a TATA box and 5 and 3' splice sites. A researcher identifies genes based on known expression. Choose ab initio annotation in a eukaryotic genome ab initio annotation in a prokaryotic genome homology-based annotation ab initio annotation to investigate a gene's function

How may internet information access benefit people's health? What distinguishes telesurgery from telemedicine?

You have assembled a new prokaryotic genome and are annotating the genes.  If you were to search for highly conserved sequences necessary for normal gene expression, what type of annotation are you doing?
