When large genomes are sequenced, which of the following is true? Group of answer choices   The genomes are converted from RNA to cDNA using reverse transcriptase, and then the cDNA is sequenced.   The genomes are fragmented, the DNA fragments are sequenced by any number of methods, and the sequences assembled to provide the original complete genome.   Sanger dideoxy sequencing is never used – instead, only nanopore sequencing is used.   The assembled sequences must have all gaps closed if the genome is to be useful for the research community.

Genome annotation

The technique of linking biological information to genome sequences is termed genome annotation. Gene annotation is the method of identifying gene locations and coding sections. It helps us understand what these genes are doing in the body through establishing structural characteristics and linking them to the actions of various proteins.
