Question

How is an eukaryotic genome different from a bacterial genome? 

(a) In having enzyme reverse transcriptase 

(b) In having start and stop codons 

(c) Presence of introns 

(d) Having thymine instead of uracil

Answer 1

Correct option: (c) Presence of introns

Eukaryotic genome has introns and exons. Introns are non-coding segments of a gene, whereas exons are coding regions. During the process of RNA splicing, introns are removed and exons are joined.

Bacteria contain a single DNA molecule that makes up the entire genome.
