A template strand of DNA in a gene reads:
3' CTC CGC TTT TAG 5'
Using the codon chart, what is the sequence of amino acids that is produced after translation?
Gln - Ala - Asn - Met
Leu - Arg - Phe - Stop
Glu - Ala - Lys - Ile
Glu - Ala - Lys - Thr
The following is an mRNA transcript. Using the codon chart, find the stop and start codons (they are not simply the first and last codons). Hint: Methionine is always the start codon. How many amino acids are going to be translated from this gene?
