Below is the RNA-like strand of DNA sequence of a gene. Red and orange letters are both exon sequences. Purple seq are the introns. How many introns and exons are there for this gene? What is the difference between red and orange letters? Could you use a pen to underline the sequences that align (ie. match) with its mRNA? Circle the \"start\" and \"stop\" codon.

Solution

7 introns and 8 exons

red regions are un translated region (3\'UTR and 5\'UTR) and orange region are translated regions of exon

the region covered the start and the end of the red region in the Given sequnece is mRNA sequnce of the gene.

after red region stops ATG is the start codon and last of the orange region TGA is the stop codon
