Question

A simple way to retrieve sequences of viral and other extra-chromosomal genetic elements such as organelles is through the National Center for Biotechnology Information (NCBI).

(a) True

(b) False

The question was asked in an online quiz.

This is a very interesting question from Genome Anatomy topic in chapter Collecting & Storing Sequences in Laboratory of Bioinformatics

Answer 1

Right option is (a) True

To explain: Prior to the sequencing of H. influenzae, the first free-living organism to be sequenced, a large number of viruses had been sequenced. Many of these organisms also serve as model systems for studying replication and gene expression. As an example, the nucleotide sequence of bacteriophage lambda was completed by Sanger.
