Question

Which of the following statement is true with respect to prokaryotic gene?

• A. Presence of exon and intron
• B. Non split gene
• C. Larger than eukaryotic gene
• D. More complex than eukaryotic gene

Answer 1

The correct option is B Non split gene

An interrupted gene (also called a split gene in eukaryotes) is a gene that contains expressed regions of DNA called exons, split with unexpressed regions called introns (also called intervening regions). Exons provide instructions for coding proteins, which create mRNA necessary for the synthesis of proteins.
Prokaryotic gene is non-splitting because they do not contain introns.

The introns need to be removed in eukaryotes and exons need to be joined in order to carry out protein synthesis by a process called RNA splicing. Hence, eukaryotic genes are more complex than prokaryotic.

Eukaryotic genes are larger than prokaryotic genes.
