Question

Which of the following is a wrong statement?

(a) Prokaryotes include bacteria and Archaea

(b) Prokaryotes have relatively large genomes

(c) Prokaryotes have relatively small genomes

(d) In Prokaryotes, The gene density in the genomes is high, with more than 90% of a genome sequence containing coding sequence

The question was asked in semester exam.

Question is taken from Gene Prediction in Prokaryotes in division Gene and Promoter Prediction of Bioinformatics

Answer 1

The correct choice is (b) Prokaryotes have relatively large genomes

The best I can explain: Prokaryotes have relatively small genomes with sizes ranging from0.5 to 10Mbp (1Mbp=106 bp). Each prokaryotic gene is composed of a single contiguous stretch of ORF coding for a single protein or RNA with no interruptions within a gene.
