Identify the correct statements
One approach focused on identifying all the genes that expressed as RNA-sequence annotation
Second approach of simply sequencing the whole set of genomes that contained all the coding and non-coding sequence expressed sequence tags
Sequence annotation – correlating sequence of nucleotides already known for an organism to their functions
For sequencing the total DNA from is isolated and converted into random fragments of relatively bigger sizes
