A gene encoding a membrane receptor protein is 2682 base pai

A gene encoding a membrane receptor protein is 2682 base pairs long. The mature mRNA of this gene is 1541 nucleotides long (without the polyA tail). The 5\'UTR and the 3\'UTR are 38 and 102 nucleotides, respectively. Does this gene have any introns?

Solution

Answer: Yes, this gene has introns.

Length of the gene = 2682 base pairs

Length of mature mRNA= 1541 nucleotides

Untranslated regions = 38+102= 140 nucleotides

Remaining region of the pre mRNA would account for introns.
