How would you need to modify your model to include intron removal?

If DNA is composed of Template strand 3' TAC TTT AAA GCG ATT 5' Non-template strand 5'ATG AAA TTT CGC TAA 3, then to synthesize an mRNA the non template strand is used. The pre- mRNA is formed with the help of enzyme RNA polymerase. Its sequence will be complementary to non- template strand, i.e. = 3' UAC UUU AAA GCG AUU 5'. The pre- mRNA has some coding and some non coding sequences. Coding are- exons and non- coding ones are introns. Spliceosome removes the introns- which is termed as intron splicing, the resultant mRNA is modified and ready for protein synthesis.

Thanx duddy .. I'm clear now
