Question

Below is a partial DNA sequence from a coding gene in a diploid eukaryote. The DNA sequence spans two introns and two exons. Nucleotides that code for exon nucleotides are given in normal font, CAPITAL LETTERS. Nucleotides that code for intron nucleotides are given in normal font, lower case letters.

Original DNA:

3’ g t c A C A C G T T T A c a c g t t a a a c a t c G C G A A G T T T 5’

Below, assuming that the first letter of the mature mRNA is the first letter of a codon, give the amino acid sequence that would result from translation of the mature mRNA.

Explanation / Answer

codons for 3’ g t c A C A C G T T T A c a c g t t a a a c a t c G C G A A G T T T 5’   DNA

                  5' UGU, GCA ,AAU, CGC UUC AAA 3' mRNA

                  Cysteine, Alanine, Asparagine, Argenine, phenyl Alanine, Lysine
